It can be frustrating to encounter a dishwasher that suddenly loses power, and of course, the problem arises when the appliance is loaded with dirty dishes.
So, your dishwasher is not lighting up and is ignoring your commands. Likely, it's just not getting any power. But before you panic and call a repair professional, let's try some troubleshooting steps together.
There are multiple answers to why your dishwasher will not turn on. In this article, we delve into the top reasons why your dishwasher may have lost power, offering insights and tips to help you diagnose and resolve the issue efficiently.
1. Check the power supply
If the dishwasher won’t turn on, it is natural to suspect a fault in the power supply. Several different reasons could prevent the appliance from getting electrical power.
For example, a tripped circuit breaker, bad electrical outlet, faulty wiring, and even the probability that the dishwasher isn’t properly plugged into its wall outlet.
2. Inspect the door latch
If the door latch isn't engaged, a switch stops the dishwasher from starting. Check for the latch clicking into place when you shut the door. After closing the door, tug on it to ensure a secure closure.
Examine both sides of the latch for obstacles that might hinder proper engagement or for damaged parts. A broken latch could also indicate a faulty switch.
3. Test the thermal fuse
The thermal fuse safeguards electrical parts from overheating damage. If it blows, the dishwasher shuts off.
- Locate the thermal fuse on the control board behind the inner door.
- Unplug the two connecting wires and remove the fuse from the control panel for testing.
- Adjust the multimeter to Rx1 and touch its probes to the fuse contacts.
- You should get a zero reading. Replace the thermal fuse if any other reading appears.
4. Control panel or internal component issue
Occasionally, the control unit receives power, but malfunctioning internal wiring or a defective control panel hampers the dishwasher's functionality.
In situations where the dishwasher is powered but the controls remain unresponsive, a service technician usually has to inspect and fix the control panel.
Additionally, some internal components, such as electronic control boards, switches, motors, and wiring, can break, causing a short circuit, which can also prevent the controls from getting power.
5. Check the child safety lock
Many dishwashers are equipped with a child lock function designed to prevent children from opening the appliance or altering the cycle settings. Often, the dishwasher will not start if the child lock is activated.
Typically, you can activate or deactivate the lock by pressing and holding a specific button for about three seconds or a similar action. If your dishwasher is not operating and the door won't open, refer to the manufacturer's guidelines regarding the child safety lock.
