Match the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
Show stop conditions
- Hot water cannot be drained without a scalding risk
- Water is leaking near the plug, outlet, motor, or control area
- The pump impeller is damaged, seized, or requires cabinet removal
- The code returns after the documented user-accessible checks
Likely causes
- The drain hose or household drain connection is blocked or kinked
- The drain hose is installed too high or uses an unsuitable extension
- The user-accessible drain pump or filter is obstructed
- The pump cap is not fully tightened or correctly seated
- Excess detergent has produced foam that interferes with draining
Quick checks, in order
Record the complete E36 suffix
Photograph whether the display shows E:36 -10, -25, or -26 because Bosch assigns more specific drainage guidance to the suffix.
Inspect the visible drain hose
Disconnect power, straighten visible kinks, and confirm the hose is not crushed, extended incorrectly, or installed above the model limit.
Clean only the user-accessible pump area
Follow the exact model manual, prepare for hot retained water, and confirm the pump cap is fully seated afterward.
Stop if the pump cannot be cleared safely
Repeated E36 after the accessible hose and pump checks requires model-specific pump, wiring, or control diagnosis.
Which E36 display and symptom do you have?
Check the outlet hose, installation height, pump obstruction, pump cap, and detergent foam in that order.
Bosch identifies these suffixes as a blocked drain-pump condition. Use only the manual's user-accessible cleaning procedure.
Photograph the exact suffix and arrange service; a partial blockage, pump fault, sensing issue, or control fault may remain.
Do not force the door or open the pump cap until the appliance is isolated and the manual's emergency-drain procedure is understood.
Stop and get qualified help when
- Hot water cannot be drained without a scalding risk
- Water is leaking near the plug, outlet, motor, or control area
- The pump impeller is damaged, seized, or requires cabinet removal
- The code returns after the documented user-accessible checks

Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does E36 -10 mean on a Bosch washing machine?
Bosch lists drainage-path causes including a blocked or kinked outlet hose, incorrect hose installation, a blocked pump, an incorrectly seated pump cap, and excessive detergent.
What is the difference between Bosch E36 -10 and E36 -25 or -26?
E36 -10 has several possible drainage causes. Bosch identifies E36 -25 and E36 -26 more specifically as a blocked drain-pump condition.
Can I clear Bosch E36 by unplugging the washer?
A power cycle can clear a one-time control state, but it will not remove a hose blockage, pump obstruction, installation problem, or incorrectly fitted pump cap.
