Why is My Dishwasher Making a Noise

Dishwashers are quickly becoming an essential convenience for the modern home. And while they may make our everyday lives a little bit easier, they soon become much less of a godsend if they start making an annoyingly loud noise whilst washing the dishes.

Whatever the cause for your loud dishwasher, it's often easy to fix. Here are four of the most common causes.

Bumping/Banging

This kind of noise could be the result of not loading the dishwasher correctly. Bumping and banging can also be caused by loose or worn spray arm mounts. This would result in the spray arm wobbling excessively and catching on the load baskets.  Before closing the dishwasher door give the spray arms a spin by hand and make sure they aren't catching on any crockery or cutlery.

High-Pitched Squealing

A faulty wash pump or drain pump could be the cause a high-pitched squeal. This is possibly due to water penetration, as a result of worn shaft seals. Worn spray arm bearings can also create a similar noise.

Whistling Noise

This could be the result of an unusual problem with the water inlet, at either the valve or air brake system.

Grinding Noise

There are several reasons which could explain why your dishwasher is making a grinding noise. First, check the drain, as bits of plastic and glass can gather in the drain pump and make a grinding noise as water flows through the system.

A grinding noise could also indicate that the pump is wearing out which is definitely worth checking out. If your pump or water inlet valve doesn't work properly, it could lead to water overflowing.

Dishwashers are generally robust and reliable appliances, but if yours has a fault it's always better and cheaper to replace the faulty part rather than buying a brand new appliance. Check out our range of top-brand dishwasher spares and parts.
