The E23 error on your Bosch washing machine indicates that the drain pump has failed or cannot pump water out of the drum. This error will halt the wash cycle and leave clothes sitting in water. In many cases the pump is simply blocked with a small foreign object — something you can fix yourself in 15–20 minutes without any special tools.
What Does the E23 Error Mean on a Bosch Washing Machine?
The E23 error is a drain pump fault. Bosch’s control board monitors the drain pump’s performance using current sensing and water level feedback. If the pump runs but the water level does not drop — because the impeller is blocked or the pump motor has failed — or if the pump draws no current at all (open circuit in the motor winding), the board stops the cycle and displays E23. This prevents the motor from burning out trying to pump against a blocked outlet.
Common Causes of the E23 Error
- Blocked pump filter (debris filter): Coins, hairpins, buttons, and lint accumulate in the filter at the base of the machine and eventually jam the pump impeller or block water from reaching it.
- Foreign object in the pump impeller: A small item — a coin edge, a bra underwire — can pass through the filter and lodge directly in the pump impeller, locking it mechanically.
- Kinked or blocked drain hose: The corrugated drain hose is bent, crushed, or blocked with lint, preventing water from leaving the machine even if the pump is working.
- Failed drain pump motor: The pump motor’s windings burn out after years of use, particularly if repeatedly run dry or clogged. A burnt motor needs replacement.
- Household drain blockage: If the standpipe or sink drain the machine empties into is blocked, water backs up and the E23 appears even though the machine’s own pump is functioning.
How to Fix the E23 Error: Step-by-Step
Step 1: Perform a soft reset
Turn off the washing machine and unplug it for 1–2 minutes, then restart. A brief power interruption during the drain phase can cause the control board to log a false E23. A reset clears the error and the machine will attempt to drain again on restart.
Step 2: Clean the pump filter (debris filter)
Place towels and a shallow tray on the floor in front of the machine. Open the small panel at the bottom front. Slowly unscrew the round filter cap — water will flow out, so use the tray. Once fully unscrewed, pull the filter out and remove any coins, clips, or lint. Check inside the pump housing for any items lodged at the impeller. Rinse the filter and refit tightly. This resolves the majority of Bosch E23 errors.
Step 3: Check and clear the drain hose
Disconnect the drain hose from the standpipe or sink. Blow through the hose to check for blockages. Lower the hose into a bucket and run the machine on Spin — if water flows freely into the bucket, the machine’s pump is working and the household drain is blocked. Clear the standpipe and reconnect.
Step 4: Inspect the pump impeller directly
After removing the filter, shine a torch into the pump housing. The impeller — a small plastic fan — should be visible and should turn freely when pushed with a pencil or stick. If it is stuck, a foreign object is jammed in it. Use long-nose pliers or tweezers to extract it. If the impeller rotates freely but the pump still does not run, the motor is burnt out.
When to Call a Bosch Service Technician
If the E23 error persists after cleaning the filter and checking the hose, the drain pump motor needs professional replacement. Contact Bosch India customer care (1800 266 1880) or visit an authorised Bosch service centre. Pump motor replacement typically costs ₹1,500–₹4,000 including labour and visit charge.

Frequently Asked Questions
Can the E23 error appear without an actual fault?
Yes. A power cut during the drain phase can cause the board to register a drain fault and display E23 on restart. A simple reset and restart usually resolves a power-interruption-induced E23. If the error recurs on the next normal cycle, a physical blockage or pump fault is present.
How much does it cost to fix the E23 error in India?
Cleaning the filter is free. If the pump motor needs replacement, parts cost ₹900–₹2,500 online. A Bosch-authorised service visit costs ₹500–₹1,500 as a call-out fee plus parts, totalling approximately ₹2,000–₹4,000.
Does Bosch’s warranty cover the E23 error?
Bosch’s 2-year warranty covers pump motor failure due to manufacturing defects. Blockages caused by foreign objects entering the pump are not covered as these result from objects left in clothing pockets before washing. Always empty all pockets before loading the machine to prevent debris blockages.
