Bosch Washing Machine Repair Summary: How to troubleshoot if the drum washing machine does not fill with water?
If a drum-type fully automatic washing machine does not fill with water, you should first confirm whether there is a power outage in the power grid, whether the power plug and socket are making good contact, whether the inlet hose is connected, whether the faucet is turned on, and whether the tap water supply has been interrupted. If all of the above are normal, then it can be judged that the washing machine has malfunctioned. Common fault causes and troubleshooting methods are as follows:
1. Abnormal power supply to the water inlet solenoid valve
Cut off the power, use a screwdriver to unscrew the upper cover fixing screws, remove the upper cover, and check whether the two plugs and sockets of the water inlet solenoid valve are loose. You can unplug the plug and reinsert it to ensure good contact.
2. Open circuit in the control line of the water inlet solenoid valve
Check whether the wire terminals at the drainage pump control circuit are loose, causing an open circuit in the control circuits of the water inlet solenoid valve and the drainage pump, preventing the solenoid valve from being controlled. If so, simply securing the terminals will fix the problem.
3. Water inlet solenoid valve damaged
Use a multimeter resistance range to measure the resistance value of the water inlet solenoid valve to determine if there is an open circuit or short circuit fault; if so, only a new water inlet solenoid valve can resolve the issue.
4. Fault in the water level controller
Use a multimeter resistance range to measure whether the terminals of the water level controller are already conductive. If they are not conductive, then the water level controller needs to be repaired or replaced.
5. Abnormal operation of the programmer
Check whether the wire plugs controlling the water inlet solenoid valve and the drainage pump on the programmer are making good contact. You can unplug and reinsert the plug; if the contact is good, then it may be due to abnormal operation of the programmer, which should be inspected or replaced.
