Miele Electronic Door Lock

This is an overview of the Miele dishwasher electronic door lock.

This is an expensive part, close to $300 retail and is a common failure on all models starting the 2000 series machines.


The latch arm is extended and retracted by a high quality DC motor.


The latch arm has cams that activate micro switches to tell the electronic the position of the latch.



The diagrams below are from the service manual.

The Knock 2 Open feature is present on the newest models of Miele dishwasher. It uses vibration sensors built into the power electronic to sense knocks and then use the automatic door latch to open the door.

From Miele’s website:

The perfect solution for handleless design

Not magic, but Miele: Knock2open turns dishwashing into a magical experience while delivering the perfect solution for handleless kitchen designs. “After knocking twice on the front panel of the fully integrated Miele dishwasher, the door opens by about 4 in completely on its own using an ingenious opening mechanism.” A convenience that you can enjoy every day.

Samsung Refrigerator Repair Nassau County Long Island

Here at RD Appliance Service, Corp. we take new technology seriously. Samsung is at the front line of modern refrigeration utilizing dual evaporator technology. One of the common problems with the dual evaporator refrigerators is a clogged drain in the fresh food section. This causes ice to build up and block the evaporator fan, as well as leaking water into the bottom of the fresh food section. Look closely at the image below (which is a GE refrigerator built by Samsung) and see the ice in the air ducts.


This GE branded Samsung refrigerator is showing classic signs of a clogged drain

That’s the evaporator cover,  behind it looks like this:


Frozen samsung refrigerator evaporator


The first image shows the ice build up on the evaporator itself, the second shows the ice encasing the fan. This happens because the mositure which normally goes down the drain, now blocked, stays in the compartment and the fan sucks it up.


Clogged fresh food drain Samsung refrigerator

The drain gets blocked for a few reasons. In this instance it was blocked deep in the drain. The drain runs behind the freezer. The homeowner was regulary using large volumes of ice from the icemaker, causing it to run almost constantly. Samsung refrigerators default to a super cold setting (-14°F) whenever ice production is needed. In this case that was all the time. So the drain froze.

Another reason drains clog is a clogged or detoriated “duckbill”, a rubber funnel that only lets drops of water through at a time, and prevents warm air from coming back up the drain into the cold fridge.


Old deteriorating duckbill

The image above shows an old and dried out duckbill. At RD Appliance Service, Corp. we stock replacements and always use new ones while some companies simply remove them altogether (out of ignorance or laziness). This action causes other problems that may not become apparent until much later.
