Fixed – Bosch Dishwasher Error Code E01

Bosch is one of the greatest dishwasher brands, and their products have stood the test of time. But even the best still have challenges now and then, such as dealing with dishwasher error code E01.

Error code E01 may indicate a fault in the heating element, control panel, or even frayed contacts with those components, which are responsible for signaling the components to run a cycle.

Fortunately, Bosch provides us with several troubleshooting steps that can help users avoid this error or fix the error if it occurs.

What Does E01 Mean on a Dishwasher?

The control panel board is in charge of managing each part of the Bosch dishwasher, pretty much the same as with other devices. It’s also possible that the Bosch dishwasher control board isn’t completely broken but only missing one or two chips and can be repaired. Having a service specialist at home is not that pricey; you’ll pay lower than purchasing a new board.

Error code E01 could also signify an issue with the heater due to corrosion from hard water consumption. Bosch dishwasher heaters are one-piece units with spaces for hoses and nozzles. If there are no screws to separate it, you will need to replace the entire Bosch dishwasher.

Last, if your Bosch dishwasher displays dishwasher error E01, the motor controller in the power module could be broken, and you must replace the power module.

What Are the Troubleshooting Steps for Resolving Error Code E01?

Verifying the Error Code E01

Double-check that the Bosch dishwasher error code didn’t just appear by mistake. To reset the icons on the screen, disconnect the washer from the power outlet for 10-15 minutes. Turn it on and look at the display. Is the error displayed? If it is still appearing, check the heater.

Tips on How to Replace the Power Module in a Bosch Dishwasher

1. Turn off the dishwasher’s power supply.

2. Remove the toe kick panel.

3. Disconnect the dishwasher and appliance entirely. Dishwashers have power modules at the base on the right side, not behind fascia panels. As a result, to modify controls, dishwashers must be removed.

4. Remove the power module. The power module is held in place by two plastic base tabs. To remove the power module, carefully pry tabs until they clear the module, then lift the bottom of the module inward the heat pump until it clears the base.

5. Pull cover tabs open, then separate.

Should I Be Aware of Other Dishwasher Error Codes Besides E01?

Bosch Dishwasher Error Codes E14, E24, E25, E04, or E06

You probably found this article because you have an issue with your dishwasher and the error E01 appeared on the machine screen. Or perhaps it is a different error code E that appeared. There could be many challenges, whether the drain pump, drain hose, or the temperature sensor.

The control module normally instructs the power module to run the appliance’s drain, wash, and heat circuits. But it is expected that sometimes, one or more circuits may not function properly. Therefore, if a replacement board is needed, you must first remove the old one and then replace it.

Check the Power Source

Check that the Bosch dishwasher is not plugged into a power source. This is a safety precaution to prevent electrocution or other injuries.

You should also check on the electricity module, which could be malfunctioning. On some models, the top and side panels, or the exterior door skin and control panel, must be removed to access the electricity module.

Remove the screws, slide the top off, and lift off the side panels. For some models, you may need to remove the front “kick plate” to reach these.

The power module is usually located on the right side of the base near the back.

Examine for signs of damage and replace as needed.

What If I Have Followed All Steps and the Error Is Still Showing?

Your best option is to replace the control board. You’ll need to get a new right control board unit – not an inexpensive one. Always double-check that the specifications are correct. Consult with a specialist as needed.
