Reading the code

Bosch washer codes usually appear on the control display as E, F, H, a two part code, or an icon. After a simple cause is corrected, turn the washer off and unplug it for at least 30 seconds for a basic reset, then restart. CL or a child lock symbol is a status message rather than a fault, E32, F32, H:32, and E:60 -2B point to load imbalance, and some models use Temperature plus Finish in for about 3 seconds to turn child lock off.

Have the model number ready

Common questions about appliance repair

How do I reset a Bosch washer error code?

Turn the washer off, unplug it for at least 30 seconds, then reconnect it after you correct a simple cause such as a closed tap, kinked hose, unbalanced load, or door obstruction. If the same code returns, stop using the washer and contact a repair company.

Why does my Bosch washer code keep coming back after I clear it?

A repeating code usually means the control is still seeing the same condition, such as slow draining, low water flow, a leak, excess suds, or an internal sensor fault. Do not keep restarting cycles if water is leaking, the drum will not drain, or the code points to a motor, heater, pressure, flow, or control issue.

Are E codes and F codes the same on Bosch washers?

Often they are alternate display formats for the same fault, such as E18 and F18 for a drain fault or E23 and F23 for AquaStop activation. Newer models may also show two part formats such as E:30 -80, E:36 -10, E:60 -2B, H9E, or H:32.

Is CL an error code on a Bosch washer?

CL means child lock is active, so it is a status message rather than a fault. On some models, holding Temperature and Finish in for about 3 seconds turns it off.
