Bosch Dishwasher Error Codes E22

Bosch dishwashers are known for their high-quality performance and durability. However, like any other appliance, they are not completely immune to malfunctions or technical problems. One of the most common issues that Bosch dishwasher owners face is error code E22. This error code indicates a drain pump failure, which can lead to water not being drained properly from the dishwasher.

In this article, we will explore the causes and solutions for Bosch dishwasher error code E22.

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:

  1. 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.

  1. 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.

  1. 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.

  1. 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.
