Bosch 800 Series Dishwasher Error Codes (Fix Them Right Away)

Imagine this: You load up your Bosch 800 series dishwasher after a big family dinner, hit start, and walk away feeling good. Then you hear beeps and see a strange code flashing on the display. Your heart sinks because dirty dishes are waiting, and now this fancy machine seems broken. Don’t worry, you’re not alone. Many owners face these codes, but most are simple fixes you can handle yourself without calling anyone right away.

Understanding Common Bosch 800 Series Error Codes

Bosch 800 series dishwashers use error codes to point out problems clearly. These codes usually start with E followed by numbers, like E15 or E24. They appear on the display when something stops normal operation. Knowing what they mean saves time and stress.

Most codes relate to water flow, drainage, heating, or sensors. The machine runs self-checks during cycles. If it detects something off, it stops and shows the code to protect itself and your home. For example, a leak detection code might save you from water damage.

Don’t panic when you see one. Many are easy to fix at home. Start with the basics before thinking it’s a big repair. Reset the dishwasher often clears temporary glitches. Just power it off, wait a bit, and try again. This simple move fixes a surprising number of issues.

The 800 series is reliable, but like any appliance, it needs care. Regular cleaning keeps codes from popping up often. We’ll cover specific codes next so you know exactly what to do.

Reset the dishwasher first for many codes.
Check water supply and drain connections.
Clean filters and spray arms regularly.
Note the exact code for better troubleshooting.

Fixing the Dreaded E15 Error Code

The E15 error code means the dishwasher detects water where it shouldn’t be, usually in the base pan. This is a safety feature called AquaStop that prevents leaks from flooding your floor. It’s one of the most common codes owners see.

First, turn off the machine and unplug it. Tilt the dishwasher carefully or remove the kick panel to check for water in the base. If you find water, soak it up with towels. Common causes include a loose hose, cracked part, or too much foam from wrong detergent.

Next, inspect the float switch in the base. It looks like a small plastic piece that rises with water. Make sure it’s not stuck. Clean around it gently. Also check the door seal for damage or food bits that might let water escape inside.

After drying everything, plug it back in and run a short cycle without dishes. Watch for leaks. If the code comes back, the issue might need a pro to check the sensor or replace a part. But many times, a good clean and reset makes it go away for good.

Tilt unit to check for base water.
Dry thoroughly and reset.
Inspect float switch and hoses.
Run empty cycle to test.

Solving Drainage Issues: E24 and E25 Codes

E24 and E25 codes show up when the dishwasher can’t drain water properly. E24 often means a blockage in the drain hose or filter, while E25 points to a problem with the drain pump itself. Dirty dishes leave bits that clog things fast if not cleaned.

Start by checking the filter at the bottom inside the tub. Twist it out, rinse under water, and remove any gunk. Look in the sump area too for debris. A clogged filter causes most drainage codes.

Then look at the drain hose. Make sure it’s not kinked or bent sharply. It should loop up high under the sink before going down to prevent backflow. Disconnect and clean it if needed. Run hot water in the sink to clear the garbage disposal connection.

If those steps don’t help, the drain pump might be blocked or faulty. Listen for humming when it tries to drain. No sound or weak sound means a problem. Reset the machine and try again. Persistent codes usually need a technician to replace the pump.

Clean filter and sump area first.
Check and straighten drain hose.
Clear garbage disposal connection.
Listen for drain pump operation.

Dealing with Heating Problems: E09 and Similar Codes

E09 typically means the heating element has an issue or can’t heat water enough. Some models show related codes for temperature problems. Hot water helps dissolve detergent and clean better, so this code stops the cycle.

Check your home’s water heater first. Incoming water should be around 120 degrees Fahrenheit. If it’s too cold, the dishwasher works harder or fails. Run hot water at the sink before starting a cycle to help.

Inside, the heating element might have buildup from hard water. Clean the tub and look for white scale. Use a dishwasher cleaner monthly to prevent this. Also ensure the thermostat or sensor works by running a hot cycle and feeling if the tub gets warm.

If codes persist, it could be a bad element or control board. Reset the unit multiple times. Many owners fix this with vinegar runs or descaling. Call support if heating stays poor after cleaning.

Verify hot water supply temperature.
Run cleaner cycles regularly.
Check for scale buildup.
Reset and test hot cycles.

Water Inlet Troubles: E14, E16, E17 Codes

Codes like E14, E16, or E17 point to problems with water coming into the dishwasher. E14 often means flow meter issues, E16 too much water, and E17 too fast filling. These stop the machine from overfilling or underfilling.

Make sure the water valve under the sink is fully open. Check the inlet hose for kinks or twists. Clean the inlet screen where the hose connects to the dishwasher. Sediment builds up there and blocks flow.

Run a cycle and listen for water filling. It should sound steady. If it’s slow or noisy, pressure might be low. Test other faucets. Low home pressure affects filling.

Reset the machine after checks. If codes return, the water inlet valve or sensor might need replacement. But start simple, most inlet codes clear with hose and screen cleaning.

Open water valve fully.
Clean inlet hose screen.
Check for kinks in supply line.
Test home water pressure.

Door and Sensor Errors: E22 and Other Codes

E22 often signals a door latch or switch problem. The dishwasher thinks the door isn’t closed right, so it won’t start or continue. Other sensor codes might show for spray arms or controls.

Check the door closes firmly without resistance. Look for food stuck in the latch area. Clean the seal and edges. Sometimes misalignment from moving the unit causes this.

For spray arm codes like blockages, remove arms and clear holes. Food bits block spray and trigger errors. Reinstall them properly.

Reset after fixes. Run an empty cycle. If the door feels loose or latch clicks weakly, it might need adjustment or part replacement. These are usually quick checks that get things running again.

Ensure door latches properly.
Clean latch and seal areas.
Clear spray arm nozzles.
Reset and test empty cycle.

Frequently Asked Questions (FAQs)

Is it safe to keep running the dishwasher with an error code showing?

No, it’s better not to force it. Error codes exist to protect the machine and your home. Running with a code like E15 could lead to leaks or damage. Always fix the issue first or reset to see if it clears. This keeps everything safe and extends the life of your dishwasher.

Can I fix most Bosch 800 series error codes myself?

Yes, many codes respond well to simple home fixes. Things like cleaning filters, checking hoses, and resetting handle a lot of them. You only need basic tools and patience. If basic steps fail, then consider professional help to avoid bigger problems.

Do I need special tools to clean the filter?

Not at all. The filter twists out by hand in most models. Use warm water and a soft brush to clean it. No fancy tools required. Do this every month or when you see food buildup to prevent drainage codes.

Is hard water causing my heating error codes?

Hard water often leads to scale on the heating element, which triggers codes like E09. Use a dishwasher descaler or vinegar rinse monthly. It helps a ton. Also consider a water softener if hard water is a big issue in your area.

Can a kinked hose really cause error codes?

Absolutely. Even a small kink stops water flow or drainage properly. Codes like E24 or inlet errors appear fast. Always check the hoses behind the unit. Straighten them and make sure they have smooth curves for best performance.

Do I have to call support every time a code appears?

No, try troubleshooting first. Most codes have easy fixes. Only call if resets and cleaning don’t work. Have your model number ready when you do call. It speeds things up and helps them guide you better.

Is resetting the dishwasher enough for temporary glitches?

Often yes. Unplug for five minutes or flip the breaker. This clears minor electronic hiccups. Many owners fix codes this way alone. Combine it with cleaning for even better results.

Can wrong detergent trigger error codes?

Yes, especially too much or the wrong type. It creates excess suds that fool the leak sensor into showing E15. Stick to dishwasher-specific detergent and measure carefully. This small change prevents a lot of headaches.
