1. Your Bidet on the Lowest Pressure Setting

One of the reasons why Bidet Not Cleaning completely is that people are using them without understanding how they work. There has been a rapid increase in the installation of bidet toilets in recent years that’s why a lot of people are unaware of how to use bidets or bidet attachments properly.

Maybe you are unaware of the differences between the different settings of a bidet. You need to understand the difference between high-pressure settings and low-pressure settings.

Generally, high-pressure water clean more properly than low-pressure settings. Electric bidets typically come with 3-5 pressure settings. A dial on non-electric units allows you to select continuous changes in water pressure.


  • The pressure of your bidet is probably not the issue if you’re only using it manually.
  • If you are having trouble with your electric bidet, try a stronger setting. Try loading the highest setting too and see if that helps.
  • If using a setting that is uncomfortable is a noticeable effect of your resistance, use the strongest level that you feel comfortable with.
  • You can read the manual to understand the settings of your bidet.

2. Your Electric Bidet Seat Has Weak Pressure

Bidet not cleaning completely is a common issue that many people face. This could be because the bidet is not powerful enough or because the water pressure in your plumbing system is too weak. The low-pressure system is also not very effective in providing a thorough cleaning.

Many electric bidet seats can only provide weak water pressure, which is why you should consider investing in a more powerful model.


  • You should check your bidet’s manual to find out the flow rate of your bidet, which should be listed in gallons or liters per minute.
  • Check the Pressure Setting.
  • If it’s the manufacturer’s fault then replace it soon as possible.
  • Prefer trustable brand bidets and must check practical reviews of them on YouTube.

3. Maybe Bidet Nozzle is Bent and Water Pressure Get Slowed

One of the most common problems is when the nozzle is bent, which means that you cannot get a proper spray from the bidet. This could lead to poor cleaning and even clogging of your toilet.

When you bend the nozzle, it can leak into the water flow. That’s why it’s important to note that the nozzle should not be bent beyond a certain point. The most common cause of a bent nozzle is when you sit on it forcefully. When you sit on the bidet, your weight pushes down and bends the nozzle.


  • You can often fix bent nozzles by replacing them. If you are unable to replace, cleaning and reattaching them might be better alternatives.
  • We recommend that you clean the nozzle before and after each use with a bidet sprayer or toilet brush to maintain hygiene and prevent bacterial growth.
  • use a bidet with an adjustable height.
  • Install the bidet according to the manufacturer’s instructions, or get a plumber to do it

4. Bidet Nozzle has Aiming Problems

Modern high-tech bidets let you control wand position digitally, but some level of strategic body positioning is also going to be needed. Whether you’re using an electronic or non-electric version, they both require some effort on your part.

Some people have problems aiming the nozzle at their anus and genitals when using a bidet, especially if they are sitting down or standing up. This creates discomfort for users and can cause them to stop using it altogether.


For non-electric bidets, use the most gentle water pressure and wand position until you reach the desired result. Because manual bidets provide less precision, you’ll more often have to rely on your body positioning to help guide water where you want it.

  • You should try out all the wand settings and see how it feels for you. You can adjust the wand aiming on your remote or side panel to get the most coverage with it.
  • Adjust the water pressure until you find a level that works for you. Then experiment with adjusting the water pressure by turning it up or down to make adjustments.
  • You can save your preferred settings to quickly use them again. You can increase the water pressure, choose a temperature range, and change the wand position.

5. Maybe Your Bidet Water Supply Leaking

We heard more and more complaints about bidets being less efficient when someone was in the shower or washing machine was on.

When you have unexpected water demand, either from a broken pipe in your home or being away from home at a short notice, the bidet won’t stop cleaning itself.

Sometimes if the pipe is corroded then this issue can happen.

If the problem you’re experiencing is with your sprayer nozzle, make sure it’s not clogged up. If that doesn’t work, it may be time to replace the nozzle or clean out any debris that is blocking the sprayer from spraying properly.

Even if dirt gets stuck in the pipe, water flow can be reduced and since water pressure is slow, the bidet won’t be able to clean effectively.


  • Sometimes you might not find a huge issue, but you can check how much water each appliance uses at the same time. If the flow is reduced, then this might be an issue and it is in need of fixing.
  • Sometimes you may not be able to spray the water out of the nozzle. Or, it might spray out, but it might not do anything. This could be a sign of a malfunction in your device or an adjustment that needs to happen.
  • replace corroded piping with new piping that doesn’t corrode over time

6. Limited User Mobility

This issue is especially common with older adults. At least one study found that a single cleaning wasn’t enough to clean properly and thoroughly. Some people might feel inconvenienced if they cannot use their bidets due to limited mobility. However, most people find the convenience of a bidet far outweighs any negatives associated with lack of mobility.


  • You can check the above directions for aiming practice.
  • Wiping is often a challenge for people with mobility problems and risk factors, so even if they are unable to lift the toilet seat, bidets may still be an option. It can be a good idea to use a remote control if you don’t already have one.

7. Your Non-Electric Bidet Seat Has Weak Pressure

If the bidet you are buying is cheap or of cheap quality, You should not expect it will provide enough water pressure. So it can only clean up to your waistline – so you may still need to use toilet paper or a towel for your lower areas.

Most people who use a bidet want water pressure that matches what they are used to. Even if you’re in a situation where your house’s water pressure is slow, using the Non-Electric Bidet Seat might not give you enough cleanliness.


  • Be sure to check if any dirt or minerals are stuck or clogged in the bidet nozzle.
  • Generally, a Non-Electric Bidet seat has weak water pressure because it totally depends on your existing water pressure, If it’s low then you can choose an electric one for you.
  • To solve the problem of not being able to clean a bidet seat, people can look into buying an attachment or manual seat. They’ve been found to be twice as effective, three times less expensive, and can be easily installed.

8. Bidet Cleaning Nozzle Get Clogged

Bidet nozzles are exposed to the elements – some materials may be porous and can become clogged. This is not good for personal hygiene, so if a nozzle becomes clogged, it won’t be able to properly spray water on you.

It could also cause skin irritation or discomfort. If your bidet nozzle is clogged and you have to clean it off then the process can be difficult. It’s a problem that many people experience as well, with both the bidet nozzle and water supply being problematic by design.

  • Try using a plunger to unclog a clogged nozzle. Ensure you are using the right type of plunger – not all plungers work the same way.
  • You can also unclog using vinegar and water solution. To do this, mix 1/2 cup white vinegar with 1/2 cup water in a bowl or spray bottle. Spray the mixture onto the clogged areas and leave it for three minutes before rinsing off with warm water.
  • You can also use a toothbrush to scrub away any hard water deposits that have built up on the nozzle
  • You can use a bidet brush after each use.

9. Bidet Nozzle Struck by Dirt, Grime and Minerals

Another one of the most common problems with bidets is that the nozzle can become clogged with dirt, grime, and minerals. This can cause the user to not get enough water spray or even worse – it can lead to a serious infection or other health problems.

When a bidet nozzle gets dirty, it can make the whole process of cleaning your toilet bowl more difficult.


  • The nozzle needs to be cleaned regularly to prevent it from getting clogged up with dirt and minerals. This can be done by running water from a hose or by using a brush.
  • use an electronic cleaner that will scrub away all the dirt and minerals without any effort on your part.
  • Some people swear by vinegar and baking soda as a cleaning solution for the nozzle. Others use a more advanced approach with a solution of hydrogen peroxide mixed with water.

10. Because of Faulty Seat Sensor and/or Eco Mode

Many issues with the washing system can affect the quality of cleanliness. For example, faulty sensors and/or the Eco (power-saver) mode being unresponsive can give lesser-than-optimal results. It is not likely that this would be the case because most problems happen due to sensor issues. If that is the case, you should read an article on what to do when your bidet doesn’t work.

Electric bidet seats use sensors to detect when your bottom is about to sit on them, so the leak-proof system kicks into action. You don’t want a bidet that sprays water all over the place when no one is sitting down.

Many modern electric bidets operate in Eco mode when their sensor isn’t activated and the control panel/remote control has been idle for a while. This makes them more energy efficient for users that are concerned with the environment.


  • If possible, turn off the eco-mode just to cut down on unnecessary energy.
  • Make sure that the sensor is in contact with your body when sitting on any bidet. If the bidet doesn’t detect your body sitting on it, you may need to adjust where you are sitting or restart the sensor.
  • For technical issues, see if your manual gives instructions on how to override the body sensor. If it doesn’t, at least you can try these troubleshooting steps.

11. Maybe Your Bidet Has a Time Out Feature

Some bidet seats have a timeout feature that has been widely disliked. The BB Slim ONE is one for example.

With this timer, you make sure that a work session is what you need. The downside of this is that sometimes there’s little water pressure, which will make the cleaning session an inadequate one. Users are able to save time by using the time-out feature. It keeps them focused, ensuring they’re done with their work before their session is over.


  • If you’re using this bidet, be sure to return it or you’ll likely run into problems. Bidets like these that are made by TOTO only stop spraying when the user stands up or presses the “stop” button.

12. Maybe Bidet Wand is clogged and Needs Cleaning

A blocked nozzle can reduce water flow and the buildup around it can keep it from operating properly. Unfortunately, those issues often lead to other problems and the nozzle could, potentially, get stuck.

The issues we discussed in previous articles were for hard water, which can often lead to deposits getting stuck in the nozzle. When that happens, the bidet won’t aim correctly and you’ll only be able to use it correctly by turning off the faucet and then back on again.

If the nozzle is positioned incorrectly, it usually means there was a mistake with the installation process. The installation should be redone to alleviate any problems that may arise.


  • The nozzle will be blocked with gunk if the holes are clogged or partially blocked. Use a swab or pick to remove the blockage before putting a cartridge back into the dispenser.
  • If you are having trouble moving the bidet forward, make sure the nozzle is not too close. Take a look at where the mounting bracket and hardware that came with your bidet is installed.
  • Move the wand around a few times to check for any hard water deposits. If you detect any buildup, clean the crevices with a wet paper towel or toothbrush and vinegar mixed in a little water.

13. If your Nozzle Cap Missing

Whether you have a bidet with cap or not, please be careful to screw the nozzle on tight before turning the water on.

Some people experience a lot of trouble with their bidet nozzles. Most commonly, they experience situations where the water goes downwards and doesn’t give them the desired spray – this is due to a missing nozzle cap.

When the nozzle cap is not tightened properly it can reduce performance or even cause leaks. Remember to check your sprayer often & tighten the nozzle as soon as you notice a drop in performance.


  • To keep your spraying system running smoothly, remember to check your sprayer often and tighten the nozzle as soon as you notice a drop in performance.
  • If the nozzle cap is loose, try putting it on firmly. This can improve the pressure and/or accuracy of your bidet. If you lost a nozzle cap from your bidet, it might come with extra spare parts including an extra cap. However, you’ll need to source one for yourself if there are no excess parts in the box.

14. If Bidet Nozzle has bad Manufacturing

The other issues might be risk in the manufacturing process of the nozzle and its components. Some nozzles are made poorly or have defects in design which can cause injury when they malfunction or break down.

Incorrect or poor manufacturing can cause lots of problems with your bidet’s performance and may result in damage to your fixture. The nozzle must be manufactured with high-quality material in order to last for a long time. If it has bad manufacturing, it can cause problems such as clogging and leaking.


  • Purchase a bidet from trustable brands only.
  • Replace the nozzle if not working properly or contact the customer support of the manufacturer.

Can bidets spread bacteria?

In addition, bidet toilets ( nozzle surface and splay water) may be contaminated with Escherichia coli and Pseudomonas aeruginosa, which could cause health risks. They can also harbor antibiotic-resistant bacteria and make it easier for cases of infection to occur.
