Common Dishwasher Faults

Common Dishwasher Faults


Most common dishwasher faults come from incorrect loading. By taking heed of our free advice you may just avoid the cost of a visit.


We recommend that wine glasses, tumblers and all other glassware are placed in the upper basket of the dishwasher. By doing this you are protecting the glass from the temperature of the heating element, which is located in the base of the appliance under the spray arm.


Ensure glasses are placed upside down. This allows them to dry out, washes them more efficiently and will offer more physical support. To avoid water spots, stack the glasses between tines. Glasses do tend to rattle during a wash, so it’s best to avoid putting glasses too close together in the basket to help prevent cracks or breakages to the glassware.


If at the end of the cycle the glasses aren’t completely dry you can try opening the door to allow any residue to escape. Trapped residue and moisture can cause condensation & spot marks.


Hot glass can shatter when it comes into contact with a cooler surface, so always allow them to cool completely before you unload the machine.



Dishwasher leaves grit on dishes

Normally this is food residue which has been dried on. To avoid this, ensure that the inside of the dishwasher is cleaned regularly and dishes with a heavy food residue are rinsed before placing in the dishwasher.


Dishwasher unable to wash

The spray arm may be broken, check that it is able to turn properly. Also check the tube or pipe that feeds the spray arm for damage. If nothing is damaged, the circulation motor could be faulty or jammed.


Dishwasher does not clean dishes

This is a common problem and quite often comes down to varying qualities of detergents on the market, as well as simple user errors.

Check the correct cycle is being used for the type of load that is being washed, as different dishes require different settings.

Also make sure to regularly clean the inside of the dishwasher, and rinse food residue from plates before adding them to the dishwasher.


Dishwasher is noisy

Moveable parts might have become loose or broken, such as cutlery baskets, spray arms, baskets, runners & rollers.

Objects may be jammed or trapped in the drain or circulation pumps. Retrieve the items, and if it’s still noisy after this, it could be a faulty pump or circulation motor.


Dishwasher won’t drain

Plumbing outside of the dishwasher could be blocked or an object may be trapped in the drain or circulation pump. Check connections for blockages, and if it still isn’t draining, it could be a faulty drain pump or circulation motor.
