Hi, welcome to Just Answer. Sorry to hear you are having appliance trouble, I know how frustrating that can be! My name is ***** ***** I look forward to helping you!
That error means that the control sees an issue with the draining of the machine. See the attached page.
It sounds like the non return valve may be faulty and leaking if the tank is filling after it drains.
Please allow me just a few minutes to prepare some information for you, thank you!
Is the drain hose routed up so the water cannot flow back down after being discharged? See the attached page for the non-return valve. Can you inspect that for issues?
I am only available for messaging at the moment. I will send you the compete manual. Please allow me just a few minutes.
The manual is available for download at the link below.
Check that valve and the routing of the drain hose. That side tank should not be filling up at the end of the cycle.
Is there a high loop so the drain hose cannot allow water to run back down to the machine after it has drained?
See the diagram at the link below.
Are all of the outlets on that tank clean, see the attached page, page number 15-17 in that manual I sent you.
Yes, it will stop draining once air is in the pump, so all the water will never go completely out.
I think there is an issue in the tank valves.
That tank should not have that much water in it. Something is blocked somewhere. Check the hoses that lead from that tank to the sump.
Hmm, sounds like that the tank will need to be replaced then.
See the attached page.
Start a cycle and see if that solenoid is getting energized and if it opens when it does.
Okay, good. I am not sure why the tank is filling back up with water, though. Does it fill slowly and is it filling with clean water or drain water?
So the inlet valve must be getting energized to open and fill.
It seems like it, yes. I am going to get you the instructions to run a service cycle and see if it will change things at all.
The tech sheet for your model is attached.
Yes, that will be fine. We know that E24 will show up.
Okay, it sounds like that the inlet valve may be faulty and allowing water to seep in. Does it fill faster now that at the end when the tank fills?
If it won't stop filling I would cancel it after seeing the water valve is powered or leaking. Is there voltage to it?
The water inlet valve that opens to allow the dishwasher to fill, is it getting energized when it fills at the end or now when it is overflowing?
So it drained the tub but the heat exchanger is still full?
I think there is an issue with the valve, it may be intermittent or the control is not energizing it.
A control issue if a new valve does not fix it would be the next step.
Likely ,yes, the main control that is mounted on the right side down in the base of the machine.
My pleasure, thank you!
