1. Power Supply

Sometimes the electricity-related complications are the actual reason behind your dishwasher not getting started. Electricity-related complications include insufficient power supply, defective power cable, tripped circuit breaker or a blown fuse. All these things contribute and become the main culprit.


First of all check whether there is a sufficient amount of electricity flowing through the main power supply or not. Secondly, inspect the power cord carefully and look for possible damages. In case any damage is found, make a quick wire replacement. Lastly, the circuit breaker might be tripped while trying to protect your washer from damage, if it is tripped then you need to use the turn-off turn-on technique.

2. Door switch

Door switch is a safety feature which prevents your dishwasher from leaking. If it has become faulty then chances are that it will not close properly, as a result your dishwasher will also not start. Until and unless the door doesn’t click, you will be getting the same result over and over again. Along with this, an active child lock will also stop your Miele dishwasher from getting started.


Inspect the door switch and door latch thoroughly. In case any of the components is broken, replace it accordingly. Also check whether the child lock is enabled or not. If so, disable it to have your dishwasher in a running state.

3. Interior workings

It isn’t always possible to spot the damage visually. Sometimes the internal damages can lead to disturbed working of your dishwasher. To dive into the interior working of your washer, keep a close eye on the following components.

Motor Relay

The dishwasher will know when to start as soon as it receives signal from the motor relay. Due to any reason if the motor relay stops working so will your dishwasher. To make a confirmation regarding its working, take a multimeter and put it on the coil portion if you are seeing continuity then it means all is working well. In the other case, replace the motor relay.

Thermal Fuse

Another component is present by the name Thermal Fuse. Its purpose is to protect the dishwasher from getting overheated. During the process, it might get blown resulting in your dishwasher not working. Check the thermal fuse and make a quick replacement if it is faulty.

Drive Motor

You might have seen water swishing around in the dishwasher. Well, that swishing is caused by the drive motor. If this motor gets damaged or broken then you will witness no water action and no water action means improper working by your dishwasher. Experiencing loud whirring or humming noises? Well, definitely your motor isn’t working. Call an electrician to fix the motor or if it cannot be fixed then replace it.

4. Control panel

Control panel is considered to be the brain of your dishwasher. It handles all the major functionalities which concern dishwashers. All the important buttons along with settings options are present right there on the control panel. If the control panel stops working then the chances of your dishwasher to actually work are near to 0.


Check the working of your control panel. If any mysterious issue is found then you need to call a technician for it. Similarly, if the issue cannot be resolved then you need to replace the whole panel for good.

Other Issues

Other issues have the relevance with start switch, timer control or the selector switch. Along with this the issue could be with the wiring being loosen or damaged. If these issues are present then most probably your dishwasher won’t work.
