Why Bosch Dishwasher Won’t Start? Troubleshoot and Diagnosis

Bosch Dishwasher Won't Start

If you are not scared of getting your hands dirty, then DIY repair is a great way to save money on household items. To start off with the basics: If your Bosch dishwasher won’t turn on, there are some things you can do without calling in an expensive technician. So, Let’s check them out.

Bosch Dishwasher Is Not Getting Power

The Bosch dishwasher won’t turn on because the power is off.

Make sure It is Plug-In: If your dishwasher is plugged in and the power cord leading to it isn’t damaged, then there is an easy way to check if you’ve got power going through.

Test a lamp near the plug socket. If you’re certain that the problem lies with your Bosch dishwasher or its plugin point, try swapping out plugs (this may be needed for older houses). Remember to pull on both ends of an old plug, as sometimes they can wiggle loose without much pressure. Be sure not to touch live wires when changing sockets!

Dishwasher breaker tripped: If the power is on and plugged into a working socket, try flipping your Bosch dishwasher’s breaker. You may have tripped it by accident or you might have blown a fuse. Test other outlets in your home to be sure that this was an isolated incident before calling for repairs. If there are no electrical problems with any of the other sockets in your house, don’t hesitate to call up an electrician!

Check the Thermal Fuse: Bosch dishwashers usually have a thermal fuse located on the bottom of your Bosch dishwasher. A thermal fuse will shut power off if the dishwasher overheats. If the fuse blows, it’ll prevent the machine from starting. To determine if it’s defective, use a multimeter to check for continuity when measuring the fuse; and replace it with one that has continuity.

If you notice any corrosion around its terminals, replace it immediately. If not, then check all other components in order to identify the problem!

Check Door latches and Switches

The door latch is there to make sure the dishwasher doesn’t leak. When you open your dishwasher, it turns off automatically because of a switch fitted with switches that control when doors are opened and closed.

To have your machine working properly again, just close the door firmly so it activates its latches–no more leaks! Bosch dishwashers are designed to turn off whenever the door is opened. Just make sure that when you do use it, the door is firmly closed; this will allow the latch to move back into place and let everything work again.

There are a few things that can cause a dishwasher to stop working. One common problem is the switch, which will not allow the appliance to start if it detects an open door.

If the door is open, this switch will prevent your dishwasher from starting. But if it’s broken, it may stop your dishwasher as well.

Test the door’s switch with a multimeter and see if it registers continuity. If there is not any, you need to replace the switch.

Wrong Cycle Settings

Incorrect settings may sometimes be responsible for the Bosch dishwasher not starting. There are many different dishwasher models on the market, so it is important to check your dishwasher manual to see if there a delayed start or child lock setting. A control panel error code or symbol can alert you if the Bosch dishwasher is in child lock mode.

Confirm the dishwasher’s settings by touching all of the control pad buttons. If some of the button lights don’t turn on, replace them.

Water Supply Issue

When a Bosch dishwasher fails to start, the problem may be as simple as water supply. A leaky valve on one end or an open-air gap at another might lead to erratic behavior in sink hoses and faucets. It could affect flow rates, which would then prevent hot water from reaching the pump motor’s heating coil for proper operation.

Make sure the water valve is turned on, and your dishwasher is hooked up to a hose that can reach an open faucet. Make sure there is not a kink or pinch in the hose that connects to the water valve. This will restrict water flow and make things difficult for you.

Some dishwashers have an inlet valve that controls the water flow. If it is faulty, it may not pump out enough water to fill the dishwasher and activate the heating unit inside. The inlet valve is used to supply water to the dishwasher. If it malfunctions, water will not flow into the dishwasher, and it won’t start. In this case, replace it with a new valve.

Defective Timer

Timers are important for dishwashers because they allow power to flow at the proper times. If your timer is broken, it might not send voltage to the dishwasher when you need it – causing its cycles to malfunction and eventually stop altogether!

So make sure that before replacing or repairing a faulty timer, you take care of any other defective parts first (aka easier things).

Defective Drive Motor

The dishwasher’s motor is the part that circulates water to wash your dirty dishes. Electrical power for this pump comes from a timer in conjunction with a start relay, and it can be powered by electricity or gas. The dishwasher may not start when the start relay sends power to the motor because the drive motor is defective.

When your dishwasher sounds funny, you may want to check for any humming noises coming from the motor. If it makes a loud noise when running, this could indicate that the motor has seized up and will need replacing so your dishes can get clean again!

Selector Switch

On a dishwasher, the selector switch activates different settings to choose from. In some models of dishwashers, the switch may be located in the motor or fill circuit and could cause a dishwasher not to start if it were faulty.

Ensure that the switch is properly depressed before disassembling any components. You can check the contacts of the selector switch for continuity with a multimeter. If they are out of order, use the schematic diagram as a guide to repairing them.

Reset Bosch Dishwasher

If the dishwasher is not turning on, it may simply need to be reset. This can usually be done by unplugging the power cord and plugging it back in.
