Questions people ask
- What does E23 mean on a Bosch washing machine?
- Water has collected in the base of the machine and the leak protection has shut it down. No. Turn the tap off and unplug the machine. The float in the base has tripped, which means water is already where it should not be. Running another cycle pumps more water into a machine that is leaking it onto the floor. Start here: turn off the tap and unplug the machine.
- What does E23 mean on a Bosch dishwasher?
- The drain pump itself is jammed or has failed. No. Unlike a blocked filter, this one points at the pump, so repeated attempts to run a cycle put a jammed motor under load. Stop and check it rather than trying again. Start here: empty the tub and take the filter out.
Do not see your machine? We publish a brand only once its codes are confirmed against manufacturer documentation and a second independent source. That is slower than guessing, and it is the whole point of the site.
This is not a coincidence of one code: we compared every code that appears on more than one brand and found that several mean the opposite depending on the badge.
