Bosch dishwasher won't turn on

Any appliance can break down at one unfortunate moment, even if it was working perfectly just yesterday. If your dishwasher doesn't turn on after pressing the power button, don't panic or call a service technician. You can probably fix the problem yourself. We'll tell you how.

Why is the dishwasher "silent"?

If your Bosch "home assistant" suddenly stops working for no apparent reason, but doesn't notify the user of a problem with sounds or indicators, then the first thing you should do is check the power supply in the house. This is the most trivial assumption, but when the dishwasher does not start, this is the first thing you need to know before starting repairs at home.

If you don't have the time or experience, you can always call a repairman to check the equipment for damage and repair it.

A lack of power in the house is often the reason why a dishwasher won't turn on, causing housewives to worry about their beloved appliance. If there is power in the house, there are several other common causes that should be carefully checked, including why the machine may not respond to button presses or even display any indicators.

• Damage to the power cord.
• The outlet to which the dishwasher is connected is faulty.
• The machine's power button is broken.
• The power filter is damaged.
• The dishwasher control unit is faulty.

These are just a few of the possible causes of Bosch equipment malfunction, but in any situation, it's best to check these points first. You can also test the contacts and wires with a simple multimeter, if you have one at home. A tester can help pinpoint the problem if the wiring is burnt out or broken. You should also use a multimeter to examine the heating element, which may have burned out due to heavy use or sudden power surges. If this is the case, you'll need to buy a new water heating element.

Problem with the cable

Let's start with the most basic problem, which is easy to fix yourself. If the power cord is damaged, your Bosch appliance won't turn on until the problem with the cable is resolved. A common situation is when users incorrectly place the dishwasher in the house, accidentally placing it on the power cord.

This is almost impossible if a professional installs the "home assistant." Therefore, if you undertake the installation yourself, ensure the unit is leveled and doesn't interfere with any hoses or cables. Otherwise, you could end up with an unpleasant situation where a damaged power cord leaves burn marks on the floor. This is why it's so important to install the equipment carefully, monitoring every detail.

If your Bosch washing machine is already installed and still won't start, check the cable with a multimeter. Set it to ohmmeter mode and connect the tester's probes to the power cord plug. If the device shows that the cable is indeed damaged, don't try to solder, twist, or repair it in any other way. For safety, simply replace the entire cable—this will help prevent fires and other accidents.

If the multimeter shows that the cable is in good condition, then you need to move on to further steps.

Checking the capacitor

No matter how modern household appliances are, they remain sensitive to sudden power surges. Therefore, voltage issues, sudden power outages, and improper operation can cause the power capacitor in a Bosch dishwasher to fail. This can only be checked after partially disassembling the appliance and performing a thorough inspection.

• Remove the front panel of the dishwasher, which is located directly under the dishwasher door.
• Remove the side fasteners that hold the tray in place.

At this stage, be sure to place towels or rags under the machine to prevent any remaining liquid from spilling onto your floors.

• Open the door of the washing chamber and remove the waste filter with the impeller.
• Slam the door and turn the "home helper" over.
• Carefully remove the tray, having first disconnected the hoses and wires.
• Find the circulation pump - it contains the capacitor we need so much.
• Take a multimeter, pre-set to ohmmeter mode, to measure the resistance of the network capacitor.

During the inspection, it's also necessary to inspect the wiring and contacts for damage. If the capacitor is the cause of the problem, use the defective part as a sample to purchase a suitable replacement unit from the store. If the component is functional, proceed to the next step in this article.

Control board

The most likely cause at this stage is a failure of the Bosch dishwasher control board. The saddest thing is that this element is almost impossible to restore on your own, without having a wealth of experience or specialized knowledge. It's worth noting that service center technicians themselves advise against touching the part, as the risk of further damaging it is too great.

Even certified technicians have a hard time dealing with it, given the complexity of this peculiar "brain" of the dishwasher. Replacing it isn't always necessary, so it's always a good idea to consult a specialist before purchasing a new unit. If you suspect that the control module is the cause of your Bosch dishwasher's failure to start, you should contact a service center so that a professional can investigate the problem.

If it turns out that the problem is indeed with the circuit board, it might be easier to buy a new "home assistant," given the high cost of repairing and replacing the control module. The cost difference will be minimal, but you'll get a brand-new machine for your kitchen.

Approach renovations wisely, don't jump to conclusions, and always check for the most common appliance problems first. This will help you make the right decision and protect your family budget.
