The E24 was a failure to drain alarm and the E25 was triggered by me trying to run a cycle without the pump cover attached inside the unit (Bosch Ascenta). I replaced the pump (ordered Friday morning arrived Saturday afternoon with standard shipping...WOW) which consisted of removing the kickplate, disconnecting the electrical connector and rotating the pump body counter clockwise. Installed new pump in the reverse order and tested. Still had alarm but new pump was much quieter. I pulled unit out, removed drain hose and forced air (using my mouth...lol, I'm full of hot air) through the drain line. By pushing all of the water through the line and ensuring the line was not blocked I ran the cycle three more times without alarm. I'm assuming the alarm was because the drain line was blocked, and the motor was loud because it had been fighting against a stopped up/slow line for some time. All seems good now. These pumps are stupid easy to change. 5 minutes total. Part was perfect fit and arrived FAST. Good price and OEM product. Thanks APPros.
