Sometimes it happens that the door of the washing machine does not open after washing. It is not necessary to apply force in this case – below is how to competently correct this situation.
Replacing a damaged sunroof handle
To remove the hatch handle, you need to open the locked hatch.
How to unlock and open the hatch
Remove the top cover of the washing machine, tilt the machine backwards, transferring its weight to the two rear supports. The tank will deflect from the inner wall of the hatch under its own weight. Now you can put your hand to the locking device, feel the locking (blocking the opening) tab and pull it aside. That’s it, the hatch can be opened.
Remove the hatch from the hinges, unscrew the self-tapping screws around the perimeter of the hatch and carefully, sequentially in a circular motion take out of the locks, disconnecting the hatch into two halves. The handle is attached to one of the halves. Unscrew it and replace it with a new one, prepared in advance. Slowly assemble strictly in the reverse order. After completion, check the serviceability of the handle by opening and closing the hatch several times.
Malfunction of the hatch locking device (UBL)
A defective hatch locking device must be replaced. It is attached to the inside of the front wall with external self-tapping screws. To remove it, the hatch door must be unlocked (described above).
The safety catch is designed to lock the loading door during the wash cycle for safety reasons. The most common types of interlocks are those that utilize the properties of a thermocouple.
Principle of operation of the thermal lock
When the washing process starts, voltage is applied to the thermocouple. By heating the bimetallic plate, it utilizes its ability to bend instantly, closing the contacts of the circuit. This mechanically locks the loading door tab.
The hatch door handle cannot be turned. At the end of the washing program the voltage supply to the thermocouple is stopped, after 1-2 minutes the bimetallic plates will return to their place and the door tongue will be unlocked.
Causes of door lock failure
There are two main causes of UBL failure:
Physical, fatigue wear of the bimetallic plates. Bimetallic plates are designed for a certain number of bending-bending cycles, after which they become brittle, lose elasticity, and can no longer fulfill their function.
Change in the material structure of the plates, their destruction due to frequent voltage drop in the network during the washing process.
Checking the operation of the UBL
The most obvious sign of malfunction of the UBL – blocking the door even after the end of the washing program. This is a clear sign of bimetallic plate fatigue. Such a UBL must be replaced.
It is more complicated when the sign of the UBL malfunction is not obvious. For example, after pressing the “Start” button, the door is not blocked, the washing program is not started. Here there may be a faulty UBL, or the electronic module may be defective. We follow the path of least cost and first try to change the UBL. Dismantle the old one, using it as a sample, buy a new UBL (it is inexpensive).
Changing the washing machine door
In case of wear or breakage of the hinge of the door of the loading hatch, you can replace it yourself. Let us describe step by step how it happens. According to the same scheme, the entire door is replaced.
Disconnecting the door together with the hinge
First disconnect the door together with the hinge from the CMA housing. Remove the front collar of the hatch collar to bend the collar and use a wrench to fix the nut of the bolt fastening the hinge to the washing machine housing from turning. Now you can unscrew the bolt fixing the hinge and disconnect the hatch door from the housing together with the hinge.
Separating the hinge from the door
In the models of many manufacturers to separate the hinge from the door is simple: just unscrew the self-tapping screws fixing it. But in some models, you’ll have to disassemble the door to remove the hinge.
Disassembling the door
The door consists of two detachable halves, between which the hatch glass is clamped. Remove a few screws that fasten the halves together around the perimeter and try to separate them. The process may be tight, so you should try to apply force in different places. It will work!
Replacing the hinge
Take out the old hinge, put a new one in its place and reassemble the door halves, putting one on top of the other and pressing until we hear a click. Put the self-tapping screws back in place and screw them in.
Putting the door back in place
Replace the door by screwing its hinge to the washing machine body. Tuck the hatch collar onto the rim of the tank and put on the clamp.
Check the result
The door should stand without misalignment and fit tightly to the body of the washing machine. But it is even more important to check if the cuff is installed correctly (no leakage). To do this, turn on the CMA in rinse mode.
