Bosch dishwashers are equipped with a detection system that displays an error code indicating where the fault is detected. The code is normally an e or f followed by two numbers. Some common Bosch dishwasher faults are listed below…
Error Codes Explained
This signifies that your dishwasher is having motor troubles. Meaning that the motor controller is malfunctioning or has stopped working. To fix this involves replacing the power module.
Code e09
Bosch dishwasher troubleshooting for this code is a problem affecting the temperature. And points to a faulty heating element. This could result in damage to the heating circuit due to overheating. Or there may be an issue with the control board which may need replacing.
Code e15
A Bosch dishwasher error code e15 implies that the appliance believes there isn’t any water in the dishwasher. And it’s extremely likely that the dishwasher has a small leak. This leads to water collecting in the base plate at the bottom of the machine. And your Bosch dishwasher not draining at end of cycle.
When the water collects here it triggers a float in the base which then operates a microswitch. The water inlet will then be turned off. This, in turn, triggers the e15 error code.
A temporary solution is to tip the collected water out of the dishwasher. And reset the float. But you really need to locate the plastic microswitch cover and remove it. Then clean the Styrofoam disc thoroughly and replace it.
Other draining issues
If the bottom of your dishwasher is still full of dirty water you may need to clean the air gap. This is actually the most common problem that stops your dishwasher from draining. The air gap is located at the back of your sink and is usually a small hood or cylinder.
You’ll need to take off the cover and then depress the small hooks to release the small piece on top. Then you can clean out any blockages on the inside.
The water should then pump freely through the air gap and into the larger hose through to the garbage disposal. Removing all the food remnants will ensure the hose works efficiently.
A check valve may be used instead of an air gap. This prevents water from flowing back in the opposite direction. If the check valve is defective it will need replacing – as water from the sink will flow back into the dishwasher.
Sometimes the drain hose will become clogged. If this is the case the drain hose will need to be detached. Hold the hose over a bucket and run the dishwasher on the rinse cycle. If the water doesn’t drain this confirms an obstruction in the pipe.
You may need to pull out the dishwasher to inspect the pipe behind. To get to the blockage you’ll need to disconnect the brackets that connect the top of the dishwasher to the counter. And you may need to screw the feet down lower to adjust the height so that you can gain easier access.
If you have any concerns you should contact your local appliance repair specialists.
Code e22
The pump will need to be checked for any obstruction if this code is showing. Residual water can build up in the dishwasher sump pump. And the filter may be blocked by grease or food remnants.
