Error Code: E37 Difficulty: Hard
Problem: Overfilling of the machine has been detected, possibly due to a faulty pressure switch or a stuck valve.
How to Fix E37 Error (Step-by-Step)
- Unplug the washing machine from the power outlet and turn off the water supply valves to ensure safety.
- Locate the pressure switch, which is typically at the top of the machine, by removing the top panel.
- Carefully disconnect the thin rubber hose from the pressure switch. Inspect the hose for any cracks, holes, or signs of wear.
- Blow gently into the disconnected end of the hose to clear any potential blockages. You should hear air bubbling in the drum if the hose is clear.
- Reconnect the hose securely to the pressure switch and ensure the top panel is properly reinstalled.
- Plug the washer back in, turn on the water, and run a short cycle to see if the error is cleared. If the E37 error persists, the pressure switch or the main control board may be faulty and require professional service.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Washer
Bosch Washer Error E37: Use the code or symbol as the starting clue, then confirm the actual symptom before ordering parts.
- Unplug the washer before touching wiring, the lock, the pump area, or the control panel.
- Check the door lock, drain filter, inlet supply, and visible harness connections before replacing controls.
- If the code returns during the same part of the cycle, match the repair path to that stage: fill, wash, drain, spin, lock, or control response.
If the issue returns after these checks, match replacement parts to the complete Bosch model number from the appliance tag. The same code can point to different components depending on the exact model and when the failure appears.
