When your Bosch dishwasher displays the dreaded E5 error code, it’s time to get troubleshooting. This common error means there’s an overflow issue inside the dishwasher tub. The most probable culprit is a drain system clog preventing water from properly exiting after cycles. Follow this guide to systematically inspect water supply, filters, valves, switches, and drain components to safely identify and resolve the root cause of excessive water buildup.
What Does the E5 Error Code Mean?
When you see an E5 error code pop up on your Bosch dishwasher display, it means there’s likely an overflow situation happening inside the dishwasher tub. This overflow can cause leaks and water damage if not addressed.
An E5 error simply indicates that more water has entered the dishwasher than the built-in drain pump can remove. As a result, the water level has reached a critical “safety level,” triggering the error code.
There are a few specific issues that can cause this excessive water buildup:
- The dishwasher tub has fully overflowed with water
- There is a drain blockage that is not allowing water to exit properly
- A faulty part like the non-return valve is allowing water to backflow into the tub
The most common culprit is a partial or full clog in the drain path. Food debris, grease, broken glass, or other objects can get lodged in the drain hose, pump, or non-return valve. This blocks the water from draining out normally after the wash cycle.
To recap, if your Bosch dishwasher has error E5, it means:
- The safety water level inside the tub has been reached
- More water entered the tub than the drain pump can pump out
- The dishwasher has likely overflowed from the inner tub
- A clogged drain system is preventing water drainage
Now, let’s go over some preparatory safety steps you should take before tackling this repair.
Staying Safe When Fixing Your Bosch Dishwasher
Working on machines can be dangerous if you’re not careful. Let’s go over some tips to avoid problems when fixing your Bosch dishwasher. Being safe will help the repair go smoothly.
Turn Off the Power and Unplug
First, shut off power to the dishwasher at the breaker. Also, unplug it so there’s no chance of shocks while working. Accidents can happen fast, so play it safe up front.
Give It Time to Cool
If you just used the dishwasher, wait for it to cool off before starting. No one wants burnt fingers from hot parts! Letting it cool avoids this risk.
Shut Off Water
Close the water supply to the dishwasher before you begin. Have towels ready in case of drips when removing hoses. Fixing a dry system is less messy.
Light Up Your Work Area
Make sure there’s good light in your workspace. Bring in extra lights if it’s dark. Trying to see in shadows makes repairs hard and risky.
Clear Out Clutter
Remove items around the dishwasher. Too much stuff nearby can lead to tripping, so clear space to work safely.
Handle Parts With Care
Treat removed dishwasher parts gently to prevent damage. Go slowly and be careful during all repairs. Rushing leads to errors.
Read the Manual
Look at the user guide for your Bosch model before starting. Follow the company’s steps to avoid issues. Keep the manual handy as you work to look up info.
Fixing the E5 Error on Your Bosch Dishwasher
Let’s walk through how to troubleshoot an E5 error on your Bosch dishwasher step-by-step. Taking it slow and easy will help us find the problem.
Step 1: Check the Water Pressure
High water pressure can cause the dishwasher tub to overflow. Here’s how to check:
- Use a water pressure gauge to measure the pressure.
- If it’s over 120 PSI, it’s too high for the dishwasher.
- You’ll need to install a pressure-reducing valve to lower it.
Step 2: Inspect the Non-Return Valve
There’s a little valve inside that stops dirty water from flowing back into the tub. To check it:
- Remove the dishwasher tub to access the non-return valve.
- Clean out any gunk so it can move freely.
Step 3: Test the Drain Pump
The drain pump removes water from the tub. To test it:
- Unplug the dishwasher and turn off the water.
- Take off the access panel to reach the pump.
- Check if the pump has power during the drain cycle.
- If no power, the pump is faulty and needs replacing.
Step 4: Check the Drain Hose
Clogs in the drain hose can cause water to back up. To inspect:
- Disconnect the hose and check for blockages.
- Flush it out well to remove any gunk inside.
- Make sure the hose is installed without sagging or kinks.
- Replace if cracks or holes are found.
Step 5: Examine the Float Switch
This switch turns off the dishwasher when water gets too high. To check it:
- Locate the float switch and remove any debris.
- Test if it moves up and down easily.
- Replace it if the switch is faulty.
Taking it slow and checking each part will help you tackle that tricky E5 error!
