Error Code: F24 Difficulty: Hard
Problem: The water pump is blocked.
How to Fix F24 Error (Step-by-Step)
- Disconnect the dishwasher from power by unplugging it or switching off the circuit breaker.
- Shut off the water supply to the dishwasher, typically located under the sink.
- Remove the bottom dish rack, lower spray arm, and filter assembly from inside the dishwasher tub to access the drain pump cover.
- Place a towel under the pump cover and carefully pry it open to check for any visible obstructions like glass shards, food particles, or small bones. Remove any debris found.
- If no blockage is found, you will need to access the pump from underneath. Carefully pull the dishwasher out from the cabinet and lay it on its back on a soft towel or blanket.
- Remove the base cover panel. Locate the drain pump, disconnect the wire harness, and unclamp the hoses. Have a shallow pan and towels ready to catch residual water.
- Remove the old pump, which is often held in place by a few screws or a twist-lock mechanism. Install the new pump, reconnect the hoses and electrical connector, and reassemble the dishwasher in reverse order.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Dishwasher
Bosch Dishwasher Error F24: Use the code, light, or symbol as the starting clue, then confirm what the dishwasher actually does before ordering parts.
- 1. Turn power off before opening panels, reaching into the sump, touching wiring, or checking the pump, heater, valve, sensor, latch, or control area.
- 2. Confirm whether the display is a normal cycle/status symbol or a recurring fault that interrupts filling, washing, draining, drying, locking, or control response.
- 3. Start with the drain path: filter, sump, drain-pump impeller, hose routing, sink connection, pump wiring, and control output.
- 4. Clean the filter and sump, check spray-arm movement, verify water supply, inspect the drain hose and sink connection, and correct any visible blockage before replacing parts.
- 5. Run a short test cycle and watch where it fails; the exact stage matters more than the displayed word or symbol by itself.
- 6. Replace a part only after the same symptom repeats and the model-specific checks point to that part category. Match any replacement to the complete Bosch model number on the door tag.
If the issue returns after these checks, match replacement parts to the complete Bosch dishwasher model number from the door tag. The same display clue can point to different components depending on the exact model and when the failure appears.
