Bosch Washing Machine Error E:36 / -25 / -26: Drain Pump Blocked

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The drain pump is blocked by a foreign object or debris and cannot evacuate water from the drum.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Bosch washing machine.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Coin, button, underwire, or small item lodged in the pump impeller

Estimated time for safe first checks: 15–25 min.

Step-by-Step DIY Fix Guide

  1. SAFETY: Switch off and unplug the machine. Place towels on the floor.
  2. Open the pump filter access panel on the lower front of the machine.
  3. Slowly open the small drain hose to release residual water into a tray.
  4. Unscrew and remove the pump filter counter-clockwise.
  5. Clean the filter under warm water and inspect the pump cavity with a torch.
  6. Remove any foreign objects from the pump impeller using needle-nose pliers.
  7. Reinstall the filter firmly, close the panel, restore power, and run a drain cycle.

If it's still not draining

  • If the drain path looks clear but the code returns, the issue is more likely in the pump path or another less accessible restriction.
  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.

What This Error Means

E:36 / -25 / -26 on your Bosch washing machine means: The drain pump is blocked by a foreign object or debris and cannot evacuate water from the drum. The machine detects this condition via its sensors and stops the current cycle to prevent further damage. The error will remain until the underlying cause is resolved.

The most frequent cause is coin, button, underwire, or small item lodged in the pump impeller. Work through the causes listed below in order — the first cause is the most likely and the most straightforward to check.

Error E:36 / -25 / -26 is DIY-safe for most homeowners. The fix typically takes under 30 minutes and requires no specialist tools. Follow the steps below exactly — skipping steps is the most common reason the error returns.

The most visible symptom is standing water in the drum at the end of a cycle. Do not run another cycle until the blockage is cleared — standing water stresses the door seal and pump motor.

Most Likely Cause by Symptom

The Bosch washing machine may stop, pause, or refuse to complete the cycle normally.

Likely cause: Coin, button, underwire, or small item lodged in the pump impeller

Check first: SAFETY: Switch off and unplug the machine. Place towels on the floor.

Water may remain inside the drum at the end of the cycle.

Likely cause: Heavy lint or fabric snagged inside the pump housing

Check first: Open the pump filter access panel on the lower front of the machine.

The appliance may fail to start because the door or lock state cannot be confirmed.

Likely cause: Debris accumulation not caught by the pump filter

Check first: Slowly open the small drain hose to release residual water into a tray.

Common Causes

  • Coin, button, underwire, or small item lodged in the pump impeller
  • Heavy lint or fabric snagged inside the pump housing
  • Debris accumulation not caught by the pump filter

What Not to Do

  • Do not run the machine with a blocked pump — motor overheating results
