Bosch Dishwasher Not Starting Red Light Flashing [ANSWERED]

Understanding red flashing light and what to do about it is the first step to fixing your Bosch dishwasher. Not every flashing red light means a problem, but most will.

Has the little red light gone off on your Bosch dishwasher? This happens for a few reasons but is generally due to a problem with the door being open. Let’s take a look at some of the reasons your dishwasher isn’t running so that you can get it back up and running as quickly and conveniently as possible.

Many of us have a Bosch dishwasher. And while they’re engineered with advanced features, there are several problems that can occur. One of the most common is when the dishwasher fails to start and shows a flashing red light. So what exactly does this mean?

Red flashing light usually means that your dishwasher is unable to complete its cycle and there is an issue with the power supply, water flow, or dispenser. Common causes of this issue are a faulty circuit board, faulty water inlet valve, or a faulty dishwasher door switch.

Bosch’s dishwashers are well-designed and energy-efficient, but they have one big problem: Their door latches break. The problem is that they’re made of cheap plastic. It is possible to replace the entire latch assembly on your Bosch dishwasher with a simple do-it-yourself job that requires some basic tools and about 15 minutes of your time.

Bosch Dishwasher Not Starting Red Light Flashing – Troubleshoot And Diagnosis

Bosch Dishwasher Not Starting Red Light Flashing

Your Bosch dishwasher’s red light is on, and you don’t know what to do. Is something wrong with the machine? What does the blinking red light mean? Never fear — the issue is probably with the door latch, a small part that could be stuck or broken. Fortunately, we can help!

If you see a red light blinking on your Bosch dishwasher, it means that your door is open. The dishwasher uses an infrared beam to check if the door is closed, and if the beam isn’t interrupted when the wash cycle begins, a red light will flash.

The first thing to know is that if the Bosch dishwasher door latch sensor is showing a malfunction, or if the door latch itself is not working, the blinking red light will be triggered even if there is not currently an issue with the door being left open.

Reset The Control Panel

When your dishwasher stops, it’s likely due to a sensor malfunction. This can be caused by a faulty door latch or a faulty main control panel. A quick fix is to reset the main control panel — this will trick the faulty sensor into working again.

When the red alarm light is flashing on your Bosch dishwasher, there may be an issue with the door latch.

The most common reason for this issue is the control panel getting a signal from the door latch that it doesn’t recognize.

Resetting the main control panel can trick it into accepting a correct signal again, so you don’t need to purchase a replacement panel or call customer service.

If your Bosch dishwasher isn’t responding, try pressing the “start” button for about 3 to 5 seconds. This will reset the main control panel, which could solve the problem. If it doesn’t work, contact our customer support department or check the owner’s manual.

Resetting the Bosch dishwasher is a process that must be performed under specific circumstances as outlined by the manufacturer. The dishwasher can be reset if it is unable to enter its cycle or if it has an error message during or at the end of its cycle.

Older Bosch models may require the user to press and hold a different button than the “power” button. Sometimes, that button is the “drain” or the “cancel” button. This will reset the machine.

Here’s what you need to do to reset a Bosch dishwasher if it is not starting. First, if your dishwasher has a keypad, check to make sure you are pressing the key in correctly. If your dishwasher doesn’t have a keypad, check that you haven’t pressed more than one button at once.

Inspect The Door Latch

Door latches are mechanical devices that attach to the dishwasher door, and allow you to secure it shut. Usually, a sensor is connected to the door latch, which monitors whether or not the door has been closed properly. Once it confirms that the door is closed and won’t open during the wash cycle, it will signal the control panel to start the dishwasher cycle.

The dishwasher door latch creates a water-tight seal, which prevents water and debris from escaping during operation. This is especially important in places where there is a lot of humidity and exposure to weather.

If you’re having trouble with a Bosch dishwasher, it could be because of a faulty door latch. If you notice that your dishwasher won’t start a cycle or if it stops mid-cycle, check to see if the door latch is working properly. A faulty door latch could be the reason why your Bosch dishwasher won’t start.

If you’ve recently noticed that your dishwasher door is not sealing as well as it used to, there’s a good chance that one of the door latches is on its last legs. The latch can be replaced for around $10, and the repair process is relatively simple.

First, you must turn off the breaker to your dishwasher at the breaker panel.

Unplug your Bosch dishwasher from the wall if you want to work with the main control panel. Turn off power to the appliance by flipping the breaker switch in the fuse box before you remove the screws.

Find the six dishwasher screws and remove them. Gently pull the front panel away from the machine. It will be stuck to the door, so pull slowly and steadily.

Next, locate the screws holding your dishwasher to the underside of the countertop. This will likely require a screwdriver to undo. These screws are used to keep the entire machine in place so it can drain properly and thoroughly clean your dishes. To get a better view of the top of the dishwasher, you may need to slide it out from underneath your countertop.

Locate the latch assembly in your Bosch dishwasher. Typically, it is held in place with a screw on the left side. To get it out, unscrew the screws holding the door panel in place and pop out the door panel. The latch assembly will usually be screwed to the inside of the door panel.

Make sure your dishwasher is in good condition before you start. First, remove the two screws that hold the sensor to the top of the dishwasher. Next, remove the connectors in the wire harness. Then, remove the lock by removing the screws at the bottom of the dishwasher. Once all three pieces are removed, your dishwasher should be ready for installation of a new door latch.

In this step, you will replace the dishwasher’s door latch mechanism and door sensor. In order to do this, you will need to remove the door panel and wire connectors. Once the door panel is removed, use a screwdriver to remove the screws from the inside of the dishwasher. Finally, use a wrench to remove the old latch mechanism and replace it with a new one.

You’re almost done! Once you put the front panel back on the dishwasher, make sure it’s secured to the underside of your countertop. Plug your dishwasher back into an outlet and restore power. Your door latch is now fixed, so the dishwasher should be able to complete a wash cycle without triggering the sensor improperly.

Why Is My Bosch Dishwasher Blinking Red Light?

Dishwashers that blink red usually means the door is not properly closed, but this is not always the case. The dishwasher has to detect that the door is closed in order to start the cleaning cycle.

On some models you can try to reset the machine, but if the machine does not go into clean mode after resetting, it might be time for a service call.
