Er:22 says the control could not match the rhythm of the incoming mains frequency. Bosch's two service documents differ a little, and that helps: the Nexxt table blames a failing control module, while the Vision manual blames a weak power supply and tells the technician to check it. Put together, the control may not be getting a clean, steady supply. After storms and brownouts around Houston, flickering power is worth ruling out.
1. Look at how the washer is plugged in: avoid extension cords and power strips. 2. Find out whether the dryer, a heater or another big load runs on the same circuit. 3. Try a different grounded outlet, if one is nearby. 4. If the outlet is old or warm to the touch, call an electrician before using it.
A sag or flicker as power returns can confuse the sensing circuit. If the code appears only after an outage and clears, the supply was probably the cause.
A good surge protector helps against spikes, but a washer should usually plug straight into a grounded outlet. Check the manual, since some protectors are not rated for motor loads.
If the supply tests normal, the outlet is dedicated, and the code still appears, the board is the likelier cause. A technician can confirm before replacing it.
A technician diagnoses it on site and gives you the price in writing before any work starts.
