Understanding Miele, washing machines components and functionality

The Miele washing machine's door lock

This needs to be locked to start its cycle and keeps kids from opening it during use. If you can choose a program but nothing happens when pressing start, your door lock might be broken. You may even hear the faulty lock clicking.

Washing Machine Fill System Explained

The washing machine's fill system starts with a water inlet valve that leads to the soap drawer. Some machines have a water divert valve, routing water to different parts. The water then flows through the fill-to-drum hose into the machine. A pressure switch at the front measures the amount of water. This switch connects to a large bowl and small pipe. As it fills, air is pressurized and sent up to the pressure switch or one on a circuit board telling the machine its current water level.

Miele Washing machine, heating system

The heating system usually includes one or two temperature sensors, which can be mechanical thermostats or modern NTC sensors. These NTC sensors send resistance readings to the circuit board and this changes with temperature. A relay on the board activates the heater until it hits the desired temperature.


If there's a faulty heater, sensor, relay on the board, or wiring issue, then your heating won't work. Also, if the element in your heater is damaged - either being open-circuit or having too high resistance - it could trip your house's electricity supply.


Miele Washing Machine Drainage Process

The Miele washing machine's drain system works during the rinse cycle or final spin. The drum spins, flinging water out of the clothes and down to the bottom of the machine. This water goes through a sump hose that may contain a ball, which prevents your soap powder going into the pump system when filling. It then moves to the pump where it gets pressurized for removal from the machine.

On some models, this water passes through a plastic device at the back with another anti-siphon ball to prevent unwanted draining after emptying is complete. If it doesn't empty within a set time frame, an error might appear on display.

Understanding Miele Washing Machine Motor action

The Miele washing machine motor, usually located at the bottom, A tachometer attached to the motor's back informs the circuit board about its speed. During wash cycles, it rotates in either direction as directed by a relay or triac.

As the washer continues running, it enters a rinse cycle where spin speeds change based on its stage in the cycle. The speed then boosts to match what's set on the program for that portion of cleaning.


During final spin, water gets drained from high-speed rotations. As clothes dry out more, this rotation speed maxes out according to program settings - typically ranging between 800 and 1600 rpm.

Miele, washing machine suspension system

Miele washing machines have a suspension system, much like cars, with two or three legs to stabilize the drum during wash cycles. If these legs wear out or get damaged, the machine may shake and make loud noises as the drum hits the cabinet during washing, rinsing or spinning. It's important to replace worn-out legs to prevent this issue. Overloading the machine or not balancing clothes in the drum can also cause it to vibrate and produce unpleasant sounds. It also has springs at the top of the drum supporting the weight to the chassis.

Miele washing machine drums

The drum of a Miele washing machine is usually made from stainless or coated steel to prevent rust. It's attached to a three-legged spider at the back, which connects to the drum shaft and runs through seals and bearings. the drum shaft Connect to the back pulley wheel (which is connected via belt to the motor allowing rotation)

The outer part is watertight with hose access for filling or emptying.

To avoid shaking, concrete blocks or plastic-encased weights are bolted onto the sides as counterweights.

On washer-dryers, a condensing unit at the rear lets water trickle down while in dry mode, converting water vapor into liquid.

Every few years, it’s wise to check if these parts are still in good shape: bearings should be inspected for wear and tear; seals checked for leaks that could seep from. This ensures your washing machine performs optimally without any hitches.

Understanding Miele Washing Machine Electronics

The Miele washing machine's electrical system connects to the power source through a plug. A suppressor or filter regulates the electricity flow and prevents interference with other household items. The washing machine uses two circuit boards: one for programming specific to that model, and another for its display.

These circuit boards contain elements like relays, triax, resistors, diodes, capacitors etc., enabling them to control electricity supply to different parts of the machine at various times. They receive input from components such as motors tachometers and sensors like NTC, or mechanical thermostats when the program understands the information, it will increase spin, speeds, change, water levels and water temperatures according to the sensor  information.

A water pressure switch measures the amount of water in the machine at any given time. The programs are typically embedded into an EPROM system unique to each model. This board can be programmed only by engineers although pre-programmed ones may sometimes be available depending on the manufacturer.

Bad wiring or faulty devices can cause a short circuit damaging these boards beyond repair.
