Candy Grand 1600 AAA class 8kg front loader washing machine. Starts to work when switch on machine - start to hear water going through but then stops and only led lights on stain vanish and 90 minute flashes intermittently. Can anyone please help?

This could be down to a number of reasons. The most common of which is a displaced or faulty spin switch. This switch tell the machine that the lid is closed (or that the top is on a front loader). I know this may sound silly, but if you have a spin speed selector, double check to see that it's not been set to "0".
If neither of those work/fit the problem, and also if it is showing any error codes, eg. F01/F02/UNB, please let me know

you should clean the knob with alcohol careful there is spring and a small ball in it

• F1 - The level of required dryness has not been reached within the time period. Check that the correct programme has been selected
• or
• • • The thermistor resistance has drifted or the temperature scanning sequence is incorrect. The ambient temperature could be below freezing.

I can't solve this problem but have exactly same problem with erratic lights. I 'm starting to worry about possible explosion.

There are a couple of areas that I would check. FIrst, check the water inlet valve. Remove the water supply hoses and check the small screens inside the water inlet valve. Make sure they are clear of rust or debris. The solenoids can be tested for continuity using a multimeter or ohmmeter. A lack of continuity indicates a faulty solenoid. I will attach a photo for reference.
The second thing to consider is the water level switch. This diaphragm like device has a small clear plastic tube attached between the switch and the bottom of the washers outer tub. As the water level increases, so does the pressure on the air in the tube, and when it reaches a certain level it activates the switch to turn off the water. The switch can be tested with the multimeter in the same manner as the solenoids. Hope this helped and best wishes.

Time to call the selling dealer for warranty service.

Check the drain line to make sure the water does not siphon out as it enters the machine.

You may have a faulty door switch.

itcould be speed control module, If the motor was gone it would not wash.
