How to Fix Error E15 — Step by Step
- 1
Step 1: Check and Reset the Float Switch
The first step is to check the float switch, which is usually located at the bottom of the dishwasher. This switch is responsible for detecting water levels and shutting off the water supply when the desired level is reached. To reset the float switch, turn off the power to the dishwasher at the circuit breaker or fuse box. Next, locate the float switch and gently pull it out of its mounting bracket. Check for any blockages or kinks in the float arm, and make sure it's not stuck in the 'on' position. Once you've checked and cleared any blockages, reinsert the float switch and turn the power back on. If the error code persists, proceed to the next step.
💡 Pro Tip: When checking the float switch, make sure to inspect the float arm for any signs of mineral buildup or corrosion, as these can cause the switch to malfunction.

Step 2: Inspect and Replace the Water Inlet Valve
The water inlet valve is responsible for controlling the flow of water into the dishwasher. If this valve is faulty, it can cause water to leak into the base pan. To inspect the valve, turn off the power to the dishwasher and locate the water inlet valve. Use a multimeter to check the voltage and resistance of the valve. If the valve is faulty, you may need to replace it. Be sure to purchase a replacement valve that matches the original specifications and is compatible with your Bosch dishwasher model.
💡 Pro Tip: When replacing the water inlet valve, make sure to turn off the water supply to the dishwasher before starting the replacement process. This will prevent any water from flowing into the base pan and causing further damage.

Step 3: Check and Clean the Drain Hose
The drain hose is responsible for carrying wastewater out of the dishwasher and into the drain. If this hose is clogged or kinked, it can cause water to back up into the base pan. To check the drain hose, turn off the power to the dishwasher and locate the hose. Use a drain snake or plumber's auger to clear any blockages or kinks in the hose. If the hose is damaged or corroded, you may need to replace it. Be sure to purchase a replacement hose that matches the original specifications and is compatible with your Bosch dishwasher model.
💡 Pro Tip: When cleaning the drain hose, make sure to use a gentle cleaning solution and avoid using harsh chemicals or abrasive materials that can damage the hose.

Once you've checked and replaced the float switch, water inlet valve, and drain hose, it's time to check for leaks and inspect the base pan. Turn on the power to the dishwasher and run a test cycle to see if the error code persists. If the code is still present, it's possible that there's a leak somewhere in the dishwasher. Use a multimeter to check for any electrical issues and inspect the base pan for any signs of water damage or corrosion.
💡 Pro Tip: When inspecting the base pan, make sure to check for any signs of water damage or corrosion, such as mineral buildup, rust, or warping. If you find any damage, you may need to replace the base pan or have it professionally repaired.
