Bosch Washer Error Code Er:22

Er:22 indicates that the washer's control module has experienced a frequency synchronization failure. This means the main control board can no longer properly coordinate the timing signals needed to run the machine's systems. The fault is internal to the control module and requires the module to be replaced.

No, the washer should not be operated while displaying Er:22. The control module is unable to properly manage machine functions, which means wash cycles may not complete correctly and there is a risk of uncontrolled component behavior. Discontinue use until the module is replaced.

A reset is unlikely to permanently resolve Er:22 because the fault is caused by an internal hardware or firmware failure within the control module, not a temporary software glitch. The error may clear briefly after a reset but will return once the machine attempts to run a cycle. Replacing the control module is the correct fix.

If you are comfortable working with appliance electronics and disconnecting power safely, replacing the control module is a possible DIY repair. You will need to source a compatible replacement module for your specific Bosch model. However, if you are uncertain about working with appliance control boards, a qualified appliance technician should perform the repair.

Repair costs vary depending on the specific model and labor rates in your area. A replacement control module for a Bosch washer typically ranges from around $150 to $350 or more for the part alone. Adding professional labor, total repair costs generally fall between $250 and $550, though this can vary significantly by region and service provider.
