Four of the Most Common Dishwasher Problems

If your dishwasher isn’t working properly, you’ll soon start to realise how much you rely on it in your day-to-day life.

A dishwasher takes away the need to spend hours washing pots and acts as a small luxury for your home. But what happens if it suddenly breaks down and you’re in urgent use of a fully-functioning one?

Although it may cause concern, many dishwasher faults have easy solutions that don’t warrant an engineer visit and complete a repair.

We share four of the most common dishwasher problems and how to resolve them quickly:

(Please note that dishwashers should be turned off at the mains before attempting to repair!)

Dishwasher won’t drain

If your dishwasher won’t drain completely, you may be left with a small pool of water left in the bottom after a completed cycle.

This may be due to the filters in the machine being clogged. These are usually found in the base of the machine and can be kept in good by condition by regularly clearing any dirt or grime away from the area, keeping it free of debris.

If the filters are clear and your dishwasher won’t drain, the fault may lie with the drain hose being blocked. To check that they are clean, try disconnecting the drain hose and blowing through to clear any old food.


Dishwasher not drying dishes properly

If you are sure that the pots in your dishwasher have been loaded correctly to allow water to escape, the amount of rinse aid you are adding may be the reason why your dishwasher isn’t drying dishes properly.

Rinse aid is designed to ensure that your dishes dry properly once the dishwasher has completed its cleaning cycle. It works by breaking the tension of water on the surface, which then makes your evaporation process more effective and dishes drying properly.


Dishwasher not heating effectively

The heating element of your dishwasher may be the sole reason why it is not heating properly. Visible in the tub, this element controls the temperature of water being injected into a machine.

If your dishwasher is not heating effectively, the heating element may be broken or suffering from an electrical fault. This would require attention from a qualified engineer and a repair must be completed by an electrician.


Dishwasher not filling with water

One of the most frustrating dishwasher problems can occur when the unit refuses to fill with water.

The anti-flood protection may have been activated on your machine and may be the reason why your dishwasher isn’t filling with water. This has a simple fix and can be repaired by removing the plinth from beneath the dishwasher door.

There may also be a blockage between the water pump and dishwasher tub which may cause a lack of water being pumped into the unit. This can be fixed by removing the spray arms and running the dishwasher for a short amount of time to clear blockages.
