Bosch Washing Machine E13 error code

E13 means the washer is taking too long to drain. The drain pump runs past its time limit without emptying the tub, so the control stops the cycle — sometimes with the door still locked.

Also shown as: E13, E:13

Quick answer: Bosch washing machine error code E13: drain timeout fault. The most common cause is clogged drain pump filter (coins, lint, debris). Try this first — clean the drain pump filter. If that does not clear it, check the drain hose.

What causes the E13 error?

  • Clogged drain pump filter (coins, lint, debris)
  • Kinked or blocked drain hose
  • Failed drain pump
  • Blocked standpipe or household drain
  • Failing pressure switch misreading the water level
  • Excess suds slowing the drain

How to fix Bosch E13 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Clean the drain pump filter
    Find the small access panel at the lower front of the washer. Place towels and a shallow tray down, open it, and unscrew the drain cap slowly. Pull out debris — coins, hair, and lint are the usual culprits. Screw the cap back firmly.
    Safety warning: Water will pour out when you open the cap. Have towels and a tray ready.
  2. Check the drain hose
    Make sure the drain hose is not kinked or crushed behind the washer, and that it is inserted into the standpipe at the correct height (not jammed in airtight).
    Safety warning: Unplug the washer before moving it to reach the hose.
  3. Cut back on detergent
    Too much detergent causes excess suds that the pump cannot move efficiently. Use only 1 to 2 tablespoons of HE detergent per load.
  4. Run Drain and Spin to test
    After cleaning the filter, run a Drain and Spin cycle with nothing in the drum. If it completes, the clog was the cause. If E13 returns, the pump or pressure switch needs a technician.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • E13 returns with a clean filter and straight hose
  • The drain pump is silent or makes grinding noises
  • The pressure switch needs testing
  • The washer is under warranty

Frequently asked questions

The door is locked and E13 is flashing. How do I get my clothes out?

Drain the water through the pump filter access first. Once the water level drops, most models unlock the door. There is also a manual release pull near the pump on many models.

How often should I clean the drain filter?

Every 2 to 3 months, or immediately if you wash pet bedding, rugs, or items with lots of lint.

Could the pressure switch cause E13?

Yes. If the filter is clean and the pump runs, a pressure switch that misreads the water level is the next suspect — a technician can test it.
