What is Bosch Dishwasher Error Code E22?
Bosch dishwashers are equipped with a sophisticated self-diagnostic system that can detect any malfunction or error. When an error is detected, the dishwasher will display an error code on the control panel.
Error code E22 in Bosch dishwashers indicates a problem with the drain pump. The drain pump is responsible for draining the water from the dishwasher at the end of the wash cycle. If the drain pump fails, the water will not be drained properly, leading to the accumulation of water in the dishwasher, and eventually, triggering the E22 error code.
What Causes Bosch Dishwasher Error Code E22?
Several factors can cause Bosch dishwasher error code E22. Some of the most common causes include:
- Clogged Drain Hose
A clogged drain hose is one of the most common causes of Bosch dishwasher error code E22. The drain hose is responsible for carrying the water from the dishwasher to the drain. If the drain hose is clogged, the water will not be able to flow out of the dishwasher, causing the drain pump to fail and triggering the E22 error code.
- Faulty Drain Pump
A faulty drain pump is another common cause of Bosch dishwasher error code E22. The drain pump is responsible for pumping the water out of the dishwasher. If the drain pump is faulty or damaged, it will not be able to drain the water properly, leading to the accumulation of water in the dishwasher and triggering the E22 error code.
- Blocked Filter
A blocked filter is another cause of Bosch dishwasher error code E22. The filter is responsible for trapping food particles and debris from the water before it enters the dishwasher. If the filter is clogged or blocked, the water will not be able to flow properly, causing the drain pump to fail and triggering the E22 error code.
- Malfunctioning Control Board
A malfunctioning control board is a rare but possible cause of Bosch dishwasher error code E22. The control board is responsible for controlling the dishwasher’s various components, including the drain pump. If the control board malfunctions, it may send incorrect signals to the drain pump, causing it to fail and triggering the E22 error code.
How to Fix Bosch Dishwasher Error Code E22?
Fixing Bosch dishwasher error code E22 can be a simple task or a more complicated one, depending on the cause of the error. Here are some steps you can take to fix the E22 error code:
- Check the Drain Hose
The first step in fixing Bosch dishwasher error code E22 is to check the drain hose for clogs or kinks. Disconnect the drain hose from the dishwasher and check for any obstructions. If you find any clogs, remove them and reconnect the drain hose.
- Check the Drain Pump
If the drain hose is not clogged, the next step is to check the drain pump. The drain pump is located at the bottom of the dishwasher. To access the drain pump, remove the dishwasher’s bottom panel.
Once you have access to the drain pump, check for any signs of damage or wear. If the drain pump is damaged or worn, it needs to be replaced.
- Check the Filter
If the drain hose and pump are functioning properly, the next step is to check the filter. The filter is usually
located at the bottom of the dishwasher, under the spray arm. To access the filter, remove the spray arm and the filter cover.
Check the filter for any debris or food particles. If the filter is clogged, remove the debris and clean the filter thoroughly. Once the filter is clean, reassemble the dishwasher and run a cycle to see if the E22 error code has been resolved.
- Reset the Control Board
If none of the above steps resolve the E22 error code, try resetting the control board. To reset the control board, turn off the dishwasher and unplug it from the power source. Wait for a few minutes, then plug the dishwasher back in and turn it on.
If the control board was malfunctioning, resetting it may resolve the E22 error code. If the error code persists, it may be time to call a professional technician for further diagnosis and repair.
