Miele dishwashers are A+++ energy rated, making them extremely efficient. Fully integrated models have AutoOpen drying features that guarantee optimum drying, and MultiFlex trays for maximum convenience.

Automatic dispensing with integrated PowerDisk, and sophisticated handless designs are another two qualities that give these appliances all-round kitchen appeal.

When your dishwasher isn’t operating as it should it’s good to know what might be going wrong, even if you can’t fix it yourself. Look at some common Miele dishwasher problems and troubleshooting below:

Miele Dishwasher Problems

Miele Dishwasher Not Draining

If the tub on your dishwasher won’t empty this could be caused by a blocked drain pump or filter, a kinked drainage hose, or a broken impeller on the drain pump itself. A worn or split drive belt will also result in drainage issues, as can a defective motor.

If your dishwasher is connected to the waste disposal food remnants may have become lodged in the drainage pipe. Miele dishwasher problem solving, in this instance, would be to run the waste disposal alongside running the water in your kitchen sink to get rid of any obstructions.

Miele dishwasher troubleshooting also covers:

Miele Dishwasher Not Filling

When there’s a problem with the water supply this could be related to the water inlet valve. This may not be turned on completely, or it may not be working at all. If the valve is leaking or defective it will need to be replaced. A kinked hose may also be the culprit!

Inadequate water pressure can also affect the dishwasher’s ability to fill. In many cases, the pressure will return to normal of its own accord, but if it doesn’t you may need to contact your water supplier for help and advice.

Miele Dishwasher Won’t Start

This is typically an electrical fault where the circuit breaker trips every time you turn the appliance on. The power supply, power socket, fuses, and electrical wiring will all need to be checked. This is best left to a qualified engineer who will carry out safety checks and repair or replace any defective components.

Miele Dishwasher Making Knocking Noises

This indicates that the spray arm is blocked and unable to move freely. When the water isn’t sprayed the dishes simply don’t get washed. Often the cause is an item of tableware preventing proper motion, and as the spray arm turns it thumps against it. Damage to the spray arm will result in it having to be replaced. The circulation pump takes the water from the tub and forces it through the spray arm. If this part is faulty it won’t move water as it should. This is a more complex repair that needs a professional to resolve it.

Other issues could be the rattling of dishes knocking against each other, which can damage the tableware if not adjusted.
