Bosch Washer Er:13 and a Pump That Ran Too Long Without Emptying the Drum

What Er:13 means

Er:13 is the drain timeout on Nexxt and Vision front-loaders: the pump kept running past its allowed time and the drum still held water. Bosch's two service documents give three possibilities: a damaged pump, bad pump wiring, or a restriction in the hose. The filter at the lower front is the first stop, since it exists to catch exactly the debris that causes this.

Common causes of Er:13

Debris packed into the pump filter
A bend or blockage somewhere along the drain hose
Pump impeller broken, or the pump's wiring failing

✓ One safe check you can try

1. Turn the washer off and unplug it. 2. Open the flap at the lower front, lay down towels and set a tray beneath the filter. 3. Unscrew the filter a little at a time so the water drains in stages. 4. Remove coins, buttons and hairpins, rinse the filter and its housing, then screw it back in straight.

! Why to stop there

Water released from the filter can flood a floor quickly if you open it all at once.
Reaching into the housing with a screwdriver can crack the pump impeller.
A filter that is not seated properly is a common cause of leaks after a clean-out.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Er:13Er:13 questions

What should I look for when I clean the filter?

Coins, buttons, pins, lint and bits of tissue. Also check that the impeller behind the filter spins freely by turning it with a finger once the machine is unplugged.

Is Er:13 the same as the Nexxt E-codes?

It plays the same role as the drain-timeout errors on other Bosch washers. The Er:13 version belongs to the Nexxt and Vision generation. Check which prefix your display uses before comparing notes with other owners.

How often does the filter need attention?

Twice a year suits most homes. Check it sooner if you wash work clothes with full pockets or pet bedding. The job takes about ten minutes and heads off most drain errors, so it is worth putting on the calendar.
