Try first to reset the error follow the procedures below.


  • Hold down program selection button for up to ten seconds
  • Close the door.
  • After approximately 1 minute the dishwasher will advance to the end
    of cycle.

  • Turn off power from main circuit breaker.
  • Dry water inside the dishwasher.
  • Clean the filter unit (see Manual here, page 26 )
  • Apply power back.

3) If that does not work, please try the following procedure, it should enter diagnostic mode and reset the error.

  • Switch off the appliance
  • Turn the dishwasher back on.
  • Before any of the lights coming on press immediately the program button. Program button must be pressed 4 times within 4 seconds.
  • The two last program lights (normal and intensive) should start flashing.
  • Press again the program button once.
  • The Normal light will turn off.
  • The last light will keep flashing.
  • Switch off the appliance.
  • Wait 10 seconds.
  • Switch the appliance back-on.
If error is still there, then the problem is water pump malfunction. This will turn on second and third light from the left (light wash and regular wash)

The appliance cannot pump out the water. Check that the drain hose is not kinked or crushed and that the siphon and filter are not fouled. Check height of the drain hose at the back. Clean the drain well and filter located on the bottom panel of the machine. If the problem persists, contact the after- sales service. The pump must be accessed, freeing the hose connected to the pump from blockage, and testing the pump motor.

Note if lights are instead first (soak) and third (regular), then the problem is water inlet. In that case check pressure from the house, inlet hose. If that does not fix the problem, then the inlet valve and water level switch must be tested.

If lights are Delicate and Normal (the one with glasses and the one with dishes), then the problem is drain.

My top dishwasher drawer won't finish through the cycle. It runs fine on rinse only but not any of the wash cycles. It stops mid cycles, beeps like it has been paused, then tries to start again

Try to feel the temperature of water inside the dishwasher. If it is normal room temperature for the hot wash cycles then it is likely the heater is faulty.
It is not easy to replace unless you have good experience with repairing dishwashers.

913T Dishwasher Stops after 10 seconds

913T is a very old model (1996), I have one, I'm not a repairer, I have the same fault. It doesn't have drawers or infrared or a display.
I've just shortened the ribbon cable, which had pinch damage at the door close pinch point. I used a male & female ribbon squeeze connector pair to make a good clean joint. With the cable fault it wasn't even starting the drain cycle. Now it does start, but then long beeps, and I suspect it's detecting a fault with the motor or a sensor or faulty wire, and is halting.
I've found running the rinse cycle first then allows the main wash cycle to run, no longer stopping at 10 seconds (after the initial drain), just as the first power wash commences.
