A system failure is most likely the reason that the dishwasher does not complete the cycle. However, you can try to fix the situation yourself. To do this, you need to force turning off the device by unplugging it for a few minutes. Then turn on the machine and start the program again.

If these actions do not fix the problem, the cause is a breakdown. This may be filters’ clogging, pump overheating, or breakdown of the heating element. You can try to clean the filter yourself, but a breakdown of a heating element or pump will require professional dishwasher repairs done by Toronto appliance repair specialists.

Possible reasons for the dishwasher repair non-stop running

If the dishwasher does not show an error code, its behavior can lead trained appliance repair professionals to certain malfunctions that have become the causes of the problem. The list of possible malfunctions causing such behavior of the dishwasher is as follows:

  • drain system blockages ;
  • malfunction or blockage of the pump;
  • inlet valve defect;
  • breakdown of the heating element or its power supply;
  • short-term or persistent failure in the control system;
  • physical defect of the control unit.

Short-term system failure

First of all, take a very close look at the symptoms of a dishwasher malfunction. When starting a short program, the machine can wash the dishes with no fail. But when starting the normal or intensive mode, it fails at the very end, leaving the dishes washed but wet. It is possible to stop the operation of the appliance only by turning it off.

When you turn on the dishwasher again, the program where the unit previously failed may refuse to start. Activating another program leads to the situation that the machine washes the dishes and fails at the very end again. Are these symptoms familiar to you? In minor details, the behavior of the machines of different brands may differ but this does not change the essence of the malfunction.

First, a short-term system failure must be excluded from the list of possible breakdowns. To do this, turn off the machine by pressing the ON/OFF button, and then de-electrify it completely by removing the plug from the socket. Wait for half an hour and then turn it on again. If there has been a system error, a reboot can fix it and the dishwasher will work as well as before.

Clogged system or pump

The second step is to check how fast the water goes down the drain. Perhaps the sewer pipe is clogged and therefore the dishwasher cannot remove the wastewater at the proper speed. If the pipe is clean, remove and check the dishwasher’s drain hose. Next, you need to clean the main filter. Also, remove the fine filter and clean it. The fine filter can be found in the bowl where the main filter is placed.

Next, you need to remove and clean the dishwasher drain pump. To get to it, you will have to turn off and pull out the machine and then remove its sidewalls. Often, a whole ball of dirt can be found on the pump impeller. If the pump is clean, it should be checked by an experienced repairman with special tools. A failed part must be replaced.

The heating element breakdown

If the dishwasher does not complete the cycle there is a chance that the heating element is broken. Not any breakdown of the heating element causing a similar behavior of the machine but only current penetration and leakage, so be careful. This can be a very dangerous breakdown so don’t delay to call for professional dishwasher repair services.
