This unit is g
not draining correctly. Unit has been flushed out and then worked for awhile and eventually gave this error code and wouldnt drain again. Im thinking drain pump?

Ahhh yes - the Bosch Ascenta; error code E24 = Drain hose blockage or pump impeller failure, suppose running it with filter unsecured would allow some goodies to get in there.

 

Here's the Bosch Repair Manual for this beast.

Changing the fine mesh filter should fix this.

I was going to check the drain pump/impellar. What do you mean changing mesh filter will fix this?

[NCARepair]

The cylinder shaped filter in the sump.

The screen is kinda flakey - if the user doesn't lock it in correctly, debris can get by it.

I have dealt with a fair number of Bosch dishwashers and have changed maybe one drain pump. Much more common problem is stuff clogging the feed to the drain pump, and/or stuff in the outgoing vent to the drain hose.

Unscrew the first filter, remove the metal plate, and then remove the mesh cylinder. Take a T15 and remove the small screw that holds the drain pump cover. Take a bunch of paper towels and a thin flat blade screwdriver and get all the popcorn seeds and other junk out of the way.

Now take a one foot long cable tie and run it up past the drain pump impeller into the tiny hole next to the impeller. This is the very small hole that faces the back of the unit. Keep moving the cable tie back and forth until you hear a "glug." You'll probably see a really disgusting lump of fat come out. Clean that up with a paper towel or a shop vac.

Put everything back together and prime with about a half-gallon of water. Hit "cancel-drain". You should hear the water gurgling as it flows out.
