Teka DW6 59 FI dishwasher won’t drain

[AberdeenBill]

Hello,

We have a problem with a Teka DW6 59 FI dishwasher (about 13 years old). A couple of days ago, we opened the dishwasher and LEDs 4 and 5 were flashing and there was water standing in the bottom of the dishwasher and nothing was very clean… The flashing lights were cleared by just pressing the Program button a couple of times. When attempting to run the dishwasher again, it seems to work for about the first five minutes, then the drain pump starts buzzing and the machine stops. There is nothing in the impeller and the motor looks like new and spins easily. The resistance across the motor terminals is about 140 Ohms. If you change program to say delicate, the dishwasher starts again and works for about five minutes. Initially, you can hear the drain pump working and water being pumped out, but then the motor stops and starts buzzing again. Any ideas??

Many thanks,
Bill

Hello again,

Further to the above… The drain hose downstream of the drain pump is not blocked and merrily spews water into the sink when the drain motor is working. The drain motor works initially but starts to buzz after 3 min and 3 seconds of each program (definitely a consistent time) and the dishwasher is full of standing water. If you open the door and press the program button for several seconds, LEDs 4 and 5 come on. When the door is closed again, the drain pump starts working again (pumping loads of water) and clears out the water before the machine stops. I have tried about 100 times to reset the machine (switch on and quickly press the program button four times) but no joy…

Could this be an issue with the main controller board?

Thanks again,
Bill
