A Guide to Common Bosch Dishwasher Error Codes in 2026

Your Bosch dishwasher is one of the more reliable appliances in a Miami kitchen. So when an error code appears mid-cycle, it’s actually useful: unlike a machine that just stops working, Bosch’s onboard diagnostics tell you exactly what the sensor detected. Understanding what each code means determines whether you need a $5 filter cleaning or a $200 pump replacement. If you need dishwasher repair in Miami, knowing the code before you call cuts the service call time significantly.

This guide covers the most common Bosch dishwasher error codes, what each one means, and whether it’s a DIY fix or a call to a technician.

💡 Did you know

Bosch estimates that roughly 60 percent of all service calls for dishwashers with E22 or E25 codes could have been resolved by the homeowner without a technician visit. The filter system and pump sump are designed for easy user access specifically to reduce these calls.

Error codes you can fix yourself

E22: blocked filter

This is the easiest fix in Bosch’s error code library. The filter system (a cylindrical filter plus a flat mesh screen) gets clogged with food particles, grease, and hard water deposits. Remove the filter assembly from the bottom of the tub by twisting it counterclockwise, rinse it under running water with a soft brush, and reinstall. This takes about 5 minutes and resolves E22 in most cases. Bosch recommends cleaning the filter every 2 to 4 weeks in homes with hard water or heavy daily use. If you’re in South Florida and running the dishwasher daily, once a month is a good cadence.

E25: drain pump blocked

E25 means the drain pump impeller is physically blocked and can’t turn. Common culprits: small bone fragments, broken glass shards, pit seeds, or paper labels from bottles. Remove the filter, then look into the pump sump area with a flashlight. Use needle-nose pliers or tweezers to remove any visible debris. Test a cycle. If the impeller spins freely after clearing the blockage, the code should go away. If E25 returns after clearing, the impeller itself may be cracked or the pump motor has failed, which requires a technician.

E15: water in base (Aquastop activation)

E15 is Bosch’s flood protection triggering. A float switch in the base detected water that shouldn’t be there. This doesn’t always mean a serious leak: condensation or a single drip from the door gasket can trigger it. To reset: tilt the dishwasher forward approximately 45 degrees to let the water in the base drain out. Lay towels down first. Once the base is empty, the float switch resets and the error clears. If E15 comes back within a few cycles, there’s a real ongoing leak and you need a technician to find and fix it.

Error codes that need a technician

E09: heating element failure

E09 means the heating element circuit is open – the element has failed and is not heating water. On older Bosch models, the heating element is at the bottom of the tub. Replacement requires draining the unit, accessing the sump, and working with the electrical harness. This is not a simple swap; it requires the right tools and knowledge of the model’s assembly. Heating element replacement in Miami typically runs $130 to $200 installed. Dishes coming out cold, or the drying cycle not working, are the practical symptoms you’d notice before the code appears.

E24: drainage fault (persistent)

E24 appearing after you’ve already cleaned the filter and confirmed the drain hose isn’t kinked usually means the pump is failing. The pump motor may have a seized bearing, or the pump impeller has cracked from debris damage. Drain pump replacement on a Bosch is a moderately involved repair: the machine typically needs to be tilted or pulled out to access the pump from the underside. Miami area labor for a pump swap runs $120 to $180 depending on the model series.

E19: diverter motor error

The diverter valve switches water flow between the upper and lower spray arms. E19 means the diverter motor has failed or is stuck. You’ll notice this as poor wash performance: either the top rack isn’t getting water or the bottom rack isn’t. This is an internal mechanical failure requiring disassembly of the wash system. Not a DIY repair on most Bosch series models.

Preventing error codes with simple maintenance

Most Bosch error codes are preventable. The filter is the most neglected maintenance item: a monthly clean prevents E22 and reduces strain on the drain pump, which in turn prevents E24 and E25. Running a dishwasher cleaner tablet (Affresh or a Bosch-brand cleaner) once a month clears mineral scale that builds up on the heating element and spray arms. In South Florida’s hard water conditions, this is more important than in most U.S. markets. The Miami area’s water typically runs 200 to 300 ppm calcium hardness, which accelerates scale buildup on every internal surface.

Check the door gasket every few months for cracks, hardening, or debris accumulation. A compromised door seal is the most common source of the E15 Aquastop activation. Wipe it with a damp cloth after the last cycle of the day; leaving water sitting in the gasket grooves accelerates the rubber’s degradation in South Florida’s heat.

💰 Save your money

A $3 bottle of dishwasher cleaner used monthly eliminates most Bosch E22 codes and significantly extends the life of the drain pump. In South Florida’s hard water, scale deposits on the heating element and pump are the root cause of 40 percent of dishwasher repair calls. Monthly cleaning costs less than one service call.

Frequently asked questions

What does error code E24 mean on a Bosch dishwasher?+

E24 means the Bosch dishwasher detected a drainage problem. Water did not drain within the expected time during the cycle. The first thing to check is the filter at the bottom of the tub: remove it, rinse it under running water, and reinstall. Also check that the drain hose at the back isn’t kinked. If neither fixes it, the drain pump impeller may be jammed with debris, or the pump itself has failed. A jammed impeller can sometimes be cleared without parts. A failed pump requires replacement, which runs $120 to $180 installed at a Miami repair shop.

How do I clear an E15 error on a Bosch dishwasher?+

E15 means the Aquastop float sensor detected water in the base of the dishwasher. This is Bosch’s anti-flood protection activating. First, tilt the dishwasher forward about 45 degrees to drain the water from the base. Lay towels down first. Once the water drains, the sensor should reset and the error should clear. If the E15 code returns after a few cycles, the source of the leak needs to be found and fixed. Common culprits are the door seal, the sump area, or a cracked spray arm. A recurring E15 is not a sensor problem – it’s a real leak.

Can I fix a Bosch dishwasher error code myself?+

Some Bosch error codes are straightforward DIY fixes. E22 (blocked filter) just requires cleaning the triple filter, which takes five minutes. E25 (drain pump blocked) often just needs debris removed from the pump impeller. E15 can sometimes be resolved by tilting the unit to drain the base. But codes like E09 (heating element failure), E19 (diverter failure), or recurring E24 after cleaning the filter require a technician. Attempting to replace a heating element or internal motor without proper tools and training risks additional damage and voids the warranty on newer units.

Why does my Bosch dishwasher keep showing error codes after resetting?+

A code that clears on reset but returns within a few cycles means the underlying fault is still present. Bosch dishwashers reset error codes when power is interrupted, but the faulty component still exists. If E24 keeps coming back after you’ve cleaned the filter and checked the hose, the pump is likely failing. If E15 recurs after tilting, there’s an ongoing leak that needs repair. Repeated error codes after reset are not a software problem – they’re the machine accurately reporting a real mechanical issue that needs repair.

How much does Bosch dishwasher repair cost in Miami?+

For most common Bosch dishwasher repairs in Miami, expect $120 to $280 total including the service call and parts. A drain pump replacement typically runs $130 to $190. Heating element replacement is $130 to $200. Control module or diverter motor repairs are more expensive, $200 to $350, depending on the model year. Bosch parts are generally available and reasonably priced. Service calls in the Miami area typically cost $60 to $90, which is usually applied to the repair cost when you proceed.
