Amana Washer Error Code rP

Pressure switch spin error

Pressure switch spin error - the electronic control detected a problem with pressure switch during spin cycle.

First step from the service manual

Check to make sure water supply faucets are on, then connect electric power and spin out any water in the washtub (may need to unplug washer for 10 seconds to clear code).

What rP means on a Amana washer

The rP error code indicates the pressure switch contacts failed to return to their closed (reset) state after the washer completed a spin and pump-out cycle. The control board monitors the pressure switch throughout the cycle, and after water is evacuated, it expects the switch to close again, confirming the drum is empty and pressure has normalized. When the switch stays open past the expected window, the board logs rP and halts further operation. The root cause is typically in the pressure switch itself, its connecting air hose, or residual water remaining in the tub.

In plain terms, your Amana washer uses a pressure switch to detect how much water is in the drum. After spinning and draining, this switch is supposed to reset to its normal closed position. If it does not, the washer throws the rP code to tell you something went wrong with that reset. This can happen because water is still sitting in the drum, the pressure switch is faulty, or the air hose that feeds water level information to the switch is kinked, clogged, or disconnected. In many cases, simply power cycling the washer and running a spin cycle clears the issue without any parts replacement.

Common causes of rP

  1. 01

    Residual water in the washtub

    Wiring / connection

    If water remains in the drum after the pump-out cycle, the pressure switch cannot return to its closed state. This can result from a slow or partial drain caused by a kinked drain hose, clogged pump filter, or low water supply pressure affecting cycle sequencing.

  2. 02

    Kinked, clogged, or disconnected pressure switch air hose

    Wiring / connection

    The small rubber air hose connecting the tub to the pressure switch can kink, accumulate soap residue, or pull loose from its fitting. Any of these conditions prevents the switch from accurately sensing that the tub is empty, keeping its contacts open.

  3. 03

    Faulty pressure switch

    Part replacement

    The pressure switch itself can fail mechanically or electrically, causing its contacts to remain open even after the tub is fully drained. A switch that does not reset correctly after pump-out will trigger rP on every spin cycle until the component is replaced.

  4. 04

    Damaged wiring harness to the pressure switch

    Part replacement

    Broken, corroded, or loose wiring between the pressure switch and the control board can mimic an open switch contact, causing the board to read the switch as never resetting. Inspecting the connector pins and harness continuity with a multimeter will confirm this cause.

Frequently asked questions about rP

What does the rP error code mean on an Amana washer?
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.
How do I fix the rP code on my Amana washer?
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.
Is it safe to keep using my Amana washer when the rP code is showing?
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.
How much does it cost to fix the rP error code on an Amana washer?
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.
Why does my Amana washer keep showing rP after I clear it?
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.
