What causes a slow cooker to make a clicking sound?
Slow cookers are a great way to make delicious meals with minimal effort required. However, clicking noises coming from your slow cooker can be quite concerning. Before you go out and buy a new pot, there are several common causes of a clicking noise that should be checked first.
Heating element cycles on and off
One of the most common causes of a clicking noise is the cycling of the heating element. The heating element of a slow cooker will switch on and off automatically in order to keep food cooking at a regular temperature. This cycling can produce a clicking sound, but it is usually nothing to worry about.
Materials expanding due to temperature changes
Another potential cause of a clicking sound coming from it is the expansion of materials due to changes in temperature. When materials such as the lid or inner lining of the cooker expand and contract when heated, they can produce clicking sounds.
Pressure valve releasing steam
The pressure valve in a cooker works to release excess steam while cooking. This is a normal process, and the valve can sometimes produce a clicking sound when releasing steam. This sound is a sign that your cooker is working correctly and is nothing to worry about.
Insufficient water
If a slow cooker does not have enough water inside it, the heating element may cycle on and off more frequently than usual in order to maintain the correct temperature. This can create clicking sounds and is a sign that the slow cooker needs more water.
Damaged gasket
The gasket on the lid of a cooker is used to create a seal and trap steam. If the gasket is damaged, steam may escape and create a clicking sound. It is important to check the gasket regularly to ensure it is not damaged.
Improper placement
If the cooker is placed on a surface which is uneven, this can cause the cooker to move around slightly and create clicking noises. It is important to ensure the slow cooker is placed on an even and stable surface to avoid this problem.

How to diagnose and fix a clicking noise from a slow cooker
If your cooker is making a clicking sound, there are several steps you can take to try and fix the problem. It is important to remember that all slow cookers are different, and the instructions that come with the cooker should be followed for the best results.
Check the heating element
The first step is to check the heating element. If the cooker doesn’t have enough water, the heating element will cycle on and off more frequently than normal and can produce a clicking sound. Check that the cooker has at least the recommended amount of water and adjust if necessary.
Check the gasket
The gasket on the lid of a cooker should be checked regularly to make sure it is in good condition. If the gasket is damaged, steam can escape and create a clicking sound. If the gasket needs replacing, it is easy to find replacement gaskets online.
Check the placement of the slow cooker
If the cooker is not placed on a level and stable surface, it can move slightly and create a clicking noise. It is important to make sure the cooker is placed on an even surface and does not move around.
How to prevent a clicking noise from a slow cooker
There are several things you can do to prevent a clicking sound from your cooker.
Use enough water
It is important to always use the recommended amount of water when using a cooker. If there isn’t enough water, the heating element may cycle on and off more quickly than normal and create a clicking sound.
Check the gasket regularly
The gasket on the lid of a cooker should be checked regularly for damage. A damaged gasket can cause steam to escape and create a clicking sound.
Place the slow cooker properly
Making sure the cooker is placed on a level and stable surface is important. An uneven surface can cause the cooker to move slightly and create a clicking noise.
A clicking noise coming from a slow cooker can be concerning, but there are several common causes and solutions. Most often, it is simply caused by the cycling of the heating element or materials expanding due to temperature changes. If these are not the cause, it is important to check that the slow cooker has enough water and that the gasket is in good condition. Making sure the slow cooker is placed on an even and stable surface is also important. By following these steps, you should be able to diagnose and fix any clicking noises coming from your slow cooker.
Expert tip:
Before using your slow cooker, it is important to check the power cord for damage. If the power cord is frayed or showing signs of wear and tear, it is best to replace it before using. By doing this, you can avoid any potential issues that may arise from a damaged power cord.
Clean the gasket
Making sure the gasket is clean can help to prevent a clicking noise. Dirt and debris can collect on the gasket over time which can impede its ability to form a seal with the lid. Regularly cleaning the gasket will ensure it is in top condition.
Check for loose parts
If a slow cooker has been moved around frequently, it is possible the parts may have become loose. This could cause them to move around slightly, resulting in a clicking noise. Make sure all of the parts are secure and not loose.
Replace the heating element
In some cases, the heating element may be worn out and need replacing. If this is the cause of the clicking sound, the new element can be easily found online.
Check for foreign objects
If you suspect that something other than the heating element is causing the clicking noise, check the inside of the slow cooker for any foreign objects. It is possible that something may have gotten into the cooker and is now hitting the sides, creating a clicking sound.
Tighten the lid
The lid of a slow cooker should not be tightened too much as this can cause the gasket to deform. However, if the lid is not tight enough, steam can escape and create a clicking noise. Make sure the lid is tight enough to create a good seal, but not so tight that it deforms the gasket.
Place on a stable surface
Placing the slow cooker on a stable surface will help to reduce the amount of movement and thus reduce any clicking noises. Make sure the surface is level and placed on a non-slip material if necessary.
Adjust the temperature setting
Some slow cookers have adjustable temperature settings. If the temperature setting is too high, the cooker can cycle on and off quickly, resulting in a clicking noise. Adjust the temperature setting to a lower level and see if this resolves the issue.
Check the cable connections
The cable connections of a slow cooker should be checked regularly to make sure they are in good condition. Worn or damaged cable connections can cause the cooker to cycle on and off more frequently and create a clicking noise.
Check for objects near the slow cooker
It is important to check for any objects near the slow cooker which could be interfering with the lid and creating a clicking sound. Move any objects away from the cooker to ensure there is nothing obstructing the lid.
Check for damage
If none of the above steps work, it is possible the slow cooker itself may be damaged. Check the cooker for any cracks or damage that may be causing the clicking noise. If the cooker is beyond repair, it may be necessary to replace it.
