I received a second-hand as-is Akso D3530 (model #107353001) dishwasher. It washes perfectly fine, but at the end of the cycle, it keeps running. It does not seem to be the drain that is running, but rather the circulating pump. I have fully emptied the pan of water (there was only a little in it (you couldn't see it until you removed the sieve) using a turkey baster and it keeps running. I also checked the float sensor in the bottom. The float sensor is not tripped, and when I manually trip it, the drain pump kicks on. If I enter the diagnostic menu and switch to "circ" it says 3.26V. Other than the entire control panel being dead, do you have any ideas what could cause this? It's not worth it to me to replace a $666 control panel on a second-hand dishwasher. I found a service manual here: http://www.servicesaver.net/Asko_Archive/asps%20dokument/Servicemanualer/Disk/Service%20Manual%20DW20%20EN.pdf. The control panel is version 20.4. Thanks.

Hi.



The overfill switch does not normally cause this problem. The overfill (float)
switch is otherwise tested by running a controlled cycle (to avoid
overfill) with float switch jumped.



The pressure sensor is located at the base of the tub, usually near to the drain well.
The pressure sensor is difficult to test with a multimeter. The part has two cut off that will open the circuit alternatively for low and high pressure. This are connected to three (or four) contacts. Ohms must be read in different pressure conditions. The PS is usually not tested using a multi-meter, but troubleshooting.

If the cycle continues with drying check also the humidity sensor located in the blower fan housing.

Here the how pressure sensor looks like.

If the appliance does not stop draining, check also that the inlet valve is not stuck open and filling all the time. The inlet valve is the water control valve connected to inlet hose. If this is leaking badly inside the tub, or if this is stuck open you get the tub filling all the time. water is detected by pressure switch and cycle does not stop draining. This would also explain the little bit of water at the bottom of the tub.

Also ensure that you have done the reset below:

Total reset
To reset the machine to its basic settings.
Fill the machine with appr. 1 litre of water!
1. Turn off the main switch (I/0)
2. Wait for at least 5 seconds
3. Keep the Programme button depressed (S1)
4. Turn on the main switch (I/0)
5. Release the Programme button (S1). Hi.

Hi.

RE:But would a broken pressure sensor make it run the circulation pump, or the drain pump?

Answer is yes. The electronic module starts the pump (or keep running) when water is detected by the pressure sensor in several parts of the cycle. At end of the cycle the pump is kept alive until the pressure sensor detects no water for several seconds.

Faulty PS is a possible cause for pump not stopping. Check also that inlet water valve is not leaking inside the tub or stuck open. In that case the pump will keep running because water keeps filling all the time. The only other situations when pump drains all the time at cycle end are because of electronic or wiring problem.
