Siemens aquastop sn65m031gb/06 pump not running

Paul answers

I will try and help with this problem...

E01 indicates water has spilled or leaked into base of machine. Unplug the unit. Pull it forward and tilt it back 45 degrees to drain out the water. try the unit again after it has dried.

E15 Fault Condition: No water in dishwasher or not sensing water.
you might find there is a blockage on the fill empty dispenser on the side this might be blocked clean thoroughly

E23 indicates a fault with the drain pump on the appliance.

Either the drain pump, wiring or main control board is faulty.

The code indicates a wrong resistance value from the pump.

In case you haven't tried it already, unplug the appliance for 10 minutes to try resetting the electronics.

If you still get E23 you'll need to begin replacing parts to try and cure the problem.
The obvious part would be the drain pump. but check if there is anything jamming the pump like piece of broken glass inside the drain hole.
