The reason for the appearance? What does it mean?
According to the data recorded in the instructions of several Bosch dishwashers models, the error e22 stands for “clogged or littered filters”. This means that the food remnants that have been washed off the plates, have hammered the filter mesh at the dishwasher bottom, or got into the dustbin and prevent the normal water drainage. As a rule, this is the main problem. A user reads an instruction, pulls out baskets for dishes, checks the mesh and finds out that it is clean. Having twisted the filter, the device’s owner finds no dirt there, too.
The fact of the error embarrasses all users. Actually, the e22 error code means clogging, but filters are clean – so what’s wrong with a dishwasher? Approximately in half of the cases, we have to get into the device deeper to find the dirt accumulated in the bowels.
If the e22 and e24 error alternate, the reason can be more complicated. In about 20% of cases, specialists indicate that this happens if the drain hose is clogged, but more often, a similar error generates a problem with the pump. Bosch dishwashers have a much weaker pump than dishwashers. However, you will spend a lot of time trying to understand where is the breakage in your dishwasher.
The e22 and e24 error, which paralyze the operation of the Bosch dishwasher, can be caused by a thread or a piece of green onion that has stuck between the impeller and the pump bushing. The reason is simple, and you can fix the problem in ten minutes unless you know how to do it.
