What is E22 error message on Bosch dishwasher

Hi Jane, water in the bottom of the dishwasher results from clogs in the filter or in the drain hose. Please make sure that you have disconnected the appliance from the mains before cleaning the filter! If your dishwasher is displaying an error code please check the meaning of the error message.

F17 is a time out fault on drain pump. Check all water hoses and drain pump for either blockage or restriction. Failing that, check your waste pipe is clear.

My mom had the same issue with her fancy bosch dishwasher! It ended up being a hose, if I remember correctly. Her problem also took two repair trips, I know for sure it was not a new motor issue. I would have someone check the hoses and the electrical panel.

E22 is residual water in sump, this could be blocked pump, dirty filter, grease build up. If you have removed white pump cover to check for blockages, ensure that it is completely clipped back into position before trying again. The non return valve maybe allowing dirty water to drain back into the machine. If you tend to run a quick wash a lot, you may need to boil a kettle and pour it into the sump to clear any build up from around the optical sensor in the sump. Post if you need further assistance

This error code is the door mechanism or the electronic panel. Mine also had it within days of purchase, got fixed. Seems to have shown up again.

F17 is a water pressure error not enough water pressure.
