Common Dishwasher Problems & Faults

Common Dishwasher Problems & Faults

On this page we're going to walk you through some of the most common dishwasher problems and faults to help you identify the possible cause of any issues. Some problems can be solved easily with a few tools, while others may require the work of a professional.

This article is meant as a basic guide and we would not advise carrying out any in depth repair work yourself. Below is a list of the most common problems that can occur to help you with your dishwasher diagnosis.

Dishwasher is leaking

If your dishwasher is leaking, the first step is to check your door and seal. Look for any damage or debris that could stop the door from sealing completely. If you see any large cracks, you will likely need to replace the door seal.

Another issue could be that the float switch, an indicator for your dishwasher’s water level, may be stuck, causing your machine to overfill and leak. If your float switch is stuck, clean it and remove anything that might be preventing it from working.

Dishwasher doesn't wash dishes

If your dishes just aren't getting cleaned, the first step is to check for any debris or blockages in the strain screen and door seal. The spray arms could also be dirty, so test them by spinning the bottom and top arms with your hand. If they don't, remove the arms and gently clean them with a toothbrush.

Dishwasher doesn't dry dishes

If your dishwasher doesn't dry dishes, you've likely got a problem with the heating element. Another possible option is the high-limit thermostat, a device that stops the dishwasher from getting too hot and stop your dishes from drying. Make sure the rinse aid dispenser is full as, without it, dishes won't dry as easily.

Dishwasher smells bad

If you're getting a bad smell from your washing machine, the culprit is likely to be caused by old food. Scour your machine for any food and clean the dishwasher’s screen. If your dishwasher is emitting a chemical smell, it's possible that a plastic plate or container has fallen down and melted onto the heating element.
