Amana Washer Error Code rP

The rP code means the pressure switch contacts did not return to their closed state after the washer finished spinning and pumping out water. The control board expects this switch to reset once the drum is empty. When it stays open, the board flags rP and stops the cycle. The most common triggers are residual water in the tub, a compromised air hose, or a worn pressure switch.

You should not run full wash cycles while the rP code is active. The code indicates the washer cannot confirm the tub is properly drained, which means it may start a new cycle with water still present or fail to complete spin cycles correctly. Running the washer in this state risks flooding, motor strain, and additional component damage. Resolve the underlying cause before resuming normal use.

A recurring rP code after clearing usually points to a pressure switch that is not resetting reliably, a partially obstructed air hose, or a drain issue that leaves water in the tub at the end of each cycle. Check the drain hose for kinks and the pump filter for debris first. If drainage looks normal, test the pressure switch with a multimeter for proper continuity and replace it if contacts do not close at zero pressure.

Start by confirming the water supply faucets are fully open, then unplug the washer for 10 seconds to clear the code. Plug it back in and run a spin-only cycle to pump out any remaining water. If the code returns, inspect the small air hose running from the tub to the pressure switch for kinks, blockages, or loose connections. If the hose is intact and the tub is draining fully, test or replace the pressure switch.

If a power cycle and drain check resolve the issue, the fix costs nothing. A replacement pressure switch is a relatively inexpensive part, typically ranging from $15 to $40 depending on the model, and is a manageable DIY repair for anyone comfortable disconnecting a wiring harness and a short air hose. If the control board or wiring harness requires repair, labor and parts from a technician can bring the cost to $150 or more.
