A dishwasher does much more than just clean dishes. It saves a lot of money, time, and energy, which can be invested in something else. It is like a significant relief to leave the utensils undone, knowing they will be cleaned independently without being bothered about it at all.

Miele produces the best dishwashers with a classic style that buyers get attracted to, but they face problems after a few years of its utility. If you, too, have a Miele product at home, then it is worth a read.

Like every happy customer of Miele, you too might have been attracted to the stylish, high-end dishwasher machines which are noiseless, wash well, and last many years beyond their life span. The Miele water inlet valve gives trouble after a few years as reviewed by most of the customers.

The main problem that occurs on a Miele dishwasher is the Waterproof System (WPS). The WPS system handles overflowing by rendering the job to another valve if one valve fails to close.

A quick replacement must be the first thought to come across but check with the Miele technical team if they are up for the service for the given warranty period.

Inspecting the Dishwasher Water Inlet Valve:

Inspecting the Dishwasher Water Inlet Valve

One can detect the flaw with the inlet valve of Miele’s dishwashers if there is an overflow from the dishwasher. It primarily arises from the leaking of the water inlet valve. 

The water supply must be disconnected. Make sure that the dishwasher is unplugged. The lower access panel can then be removed to locate the grey box of WPS located on the lower left side of the dishwasher.

Traces of wear, damage, and cracking is to be inspected visually. You can check the wiring if you have experience handling the same.

However, a visual inspection should tell you about the leakage on the spot. Any damage visually caught is considered a red alert, and that would mean immediate replacement of the Miele water inlet valve.

Many reviewers have noticed that the Miele water inlet valve problem can be identified by the red intake light blinking on the front side of the dishwasher, leading to a continuous filling and draining of water in whichever state it is.

Once this starts occurring, you can stop the water from entering the dishwasher by turning off the hot water valve under the sink.

Note: If a person is attempting to repair on his own, he should be careful of the live wires. No power supply should be there during the repair of the dishwasher water inlet valve.

Safety guidelines of Waterproof System (WPS):

Safety guidelines of Waterproof System (WPS)

Waterproof System (WPS): The Waterproof System (WPS) is a dual water inlet valve. The WPS system handles overflowing by rendering the job to another valve if one valve fails to close. One can locate two solenoids of WPS in the grey box under the sink. The grey tube inside contains the water intake hose, the wiring, and the outer sleeve.

Solenoids: The entire mechanism lies here. The solenoids open when there is water requirement through the intake hose and into the dishwasher. If the solenoids leak, then the outer sleeve protects it by channeling the water into a drip tray in the dishwasher base.

Float Switch: The float switch is a microswitch that gets activated before the accumulated water starts overflowing to stop the water intake and cuts off the water supply.

Drain Pump: The drain pump is activated to check the water’s overflow from the appliance until the machine is unplugged or till there is no water in the drip tray.

Filter and Restrictor: The water inlet valve to the WPS contains a filter and a restrictor. The filter bars the entry of large debris into the system, and the restrictor measures the right water pressure. However, the filters get clogged from time to time, which is to be cleaned after frequent intervals.
