Amana Washer Error Code bP

The bP code on an Amana washer indicates a pressure switch fill error. It means the washtub took more than 59 minutes to fill, or the pressure switch contacts were not found in the expected closed state. The washer stops the cycle to prevent damage from an incomplete fill. Checking both the water supply and the pressure switch is the recommended starting point.

Many of the common causes behind the bP code are accessible to a knowledgeable DIYer. Checking that supply valves are fully open, cleaning inlet screen filters, inspecting the pressure hose for kinks, and examining wiring connections at the pressure switch are all tasks that can be done without specialized tools. If the pressure switch or inlet valve needs replacement, those repairs are also straightforward for someone comfortable working on appliances.

Repair costs depend on the root cause. Cleaning inlet screens or adjusting supply valves costs nothing beyond your time. A replacement pressure switch or water inlet valve typically runs between $20 and $80 for the part alone, depending on the model. If a technician is needed, expect to add $100 to $200 or more in labor costs on top of any parts.

Unplugging the washer for 10 seconds can clear the bP code and allow the machine to restart. However, if the underlying cause such as a supply issue or faulty pressure switch is not resolved, the code will return during the next fill cycle. A reset is a useful first step for diagnosis, not a permanent fix.

The washer will stop its cycle when the bP code appears, so it will not continue operating normally. It is best not to attempt to force a cycle through while the error is active. If there is water sitting in the tub, running a spin cycle after unplugging and replugging the washer can help drain it so you can safely inspect the machine.
