A dishwasher that cannot drain properly is difficult to diagnose because there are many possible causes for this problem, and some are not even related to the appliance itself. Sometimes this is due to external issues that need to be resolved before calling dishwasher repair in Brampton.
What to do if there is water in the dishwasher
Water should never be in the dishwasher at the end of the wash cycle. At the end of the cycle, dirty water must be pumped out and drained down the drain.
The pump filter (drain basket) can be clogged with pieces of food, broken glass, dishes or plates. Therefore, care must be taken out when cleaning. Often when loading or unloading the dishwasher, a glass cup or something similar will break. These broken pieces fall into the dishwasher and usually end up right in the filter.
Check the drain hose for water. If it is clogged, the liquid cannot be pumped out. If it is kinked, use an anti-siphon loop in the drain hose to keep dirty water from flowing back into the dishwasher.
Check the pump inlet housing. If there’s water in there or it’s left on the bottom, you need to take the dishwasher apart to gain access to it and the salt compartment.
More often than not, the dishwasher drain hose is connected to the garbage disposal. Make sure the water flows freely into it. You should be able to hear the water draining into the bottom of the disposal.
Another problem could be a simple float mechanism that often gets stuck inside, causing the dishwasher not to drain. To make sure it’s working properly, remove the top cover and move it up and down. If the float can’t fall down, it will stop the drain cycle before it’s complete.
The dishwasher may not be installed on a level floor. The front of the appliance should have small adjustable feet. These can be adjusted so that water does not accumulate at the front. If the feet are not properly adjusted, water may be directed more toward the front of the dishwasher so it does not pump over the waste drain.
Malfunctions that require contacting a service center
We recommend that you contact a repair specialist for the following problems:
- Loose connection of parts in contact with water.
- Faulty drain pump.
- The socket to which the equipment is connected is not grounded, there is no RCD, and a network extension cord is used.
Accumulation of debris in the drain pump and its breakdown
A kink can result in a punctured drain hose. Signs of leakage in the drain hose at the kink make it easier to troubleshoot because that’s where the problem lies.
A malfunctioning food grinder in the dishwasher can lead to a build-up of food residue and, as a result, clogging the drain hose.
Pressure switch malfunction
The pressure switch is the water level sensor in the electronic module. The most complex mechanism, in the event of a breakdown, you should contact dishwasher repair in Brampton. This is the only part that requires real hands-on knowledge of such devices.
Software module failure
If the software module fails, use the following instructions:
Run the normal wash cycle. Pull up a chair or stool and sit between the dishwasher and the kitchen sink. Observe the indicators on the door and the sounds coming from the dishwasher. After the wash and rinse cycles, the appliance usually drains the used water, which goes through the drain hose leading to the sink. When the drain starts, walk over to the sink drain and watch or listen for water coming out of the dishwasher. If you can’t confirm the drain, then the sink drain is clogged. Run the disposal to try to clear the obstruction. Do not put your hand or dishes down the drain.
Refer to the error code on most dishwashers’ LCD displays. Some models will show errors that have been automatically detected in the drain system. For example, “Error 1” refers to the drain valve, and this indicates that it is working when in fact it should be turned off. Again, check your user manual for error codes specific to your model.
