Bosch Washer Error Code Er:13

Er:13 means the drain pump ran longer than the allowed time limit without successfully draining the water from the drum. The washer stops the cycle and displays this code to prevent the pump from running indefinitely. Common causes include a blocked drain hose, a clogged pump impeller, a failing pump motor, or a wiring harness fault. Diagnostic test P15 is used to evaluate the pump directly.

You should not continue running cycles while Er:13 is active. The washer has halted because it cannot drain properly, and running additional cycles risks leaving standing water in the drum, potential motor overheating, and water damage if a hose or pump seal is also compromised. Resolve the drainage issue before resuming normal use.

Repair costs depend on the cause. Clearing a blocked hose or pump filter costs nothing beyond your time. A replacement drain pump typically runs between $40 and $120 for the part alone, with professional labor adding $80 to $200 depending on your area. Wiring harness repairs fall in a similar labor range, with parts costs varying by harness configuration.

In many cases, yes. Start by checking the drain hose for kinks or blockages and cleaning out the pump filter, which is accessible on most Bosch front-load washers without special tools. If the hose and filter are clear but the error returns, further diagnosis with test P15 and harness continuity checks is needed, which may require a technician. Replacing the pump or harness is a moderately advanced repair but is achievable for experienced DIYers.

A reset may temporarily clear the display, but the code will return if the underlying drain problem is not fixed. To reset, power the machine off, wait a minute, and restart. If the root cause, such as a blocked hose or faulty pump, is still present, Er:13 will reappear as soon as the washer attempts to drain again.
