What Hr means on a Amana washer
The Hr error code on an Amana washer indicates a heater relay failure, specifically that the machine control board is not detecting the expected Heater Relay Check signal. This signal is a feedback loop built into the control circuit: when the control board energizes the heater relay, it simultaneously monitors a return signal to confirm the relay has activated correctly. If that confirmation signal is absent or falls outside the expected parameters, the board flags the Hr fault and typically halts the cycle to prevent unsafe operation.
The heater relay itself is integrated into or directly controlled by the machine control board. Because the relay and its associated check circuitry are internal to the control board assembly in most Amana washer designs, a failure in the relay driver, the feedback trace, or the relay coil itself will all produce this same error. External wiring or harness faults between the board and any heating element can also interrupt the check signal path, though the most common root cause is a failed component on the control board itself.
Because the diagnostic path points directly to the machine control board as the first and primary corrective step, technicians should inspect the board for visible damage such as burned relay contacts, heat discoloration, or cracked solder joints before ordering a replacement. Harness connections at the board should also be checked for corrosion or looseness, as a poor connection can mimic a relay failure. If the board shows no visible defects and connections are secure, board replacement is the recommended resolution.

Common causes of Hr
- 01
Failed machine control board
Part replacementThe heater relay and its check circuit are located on the machine control board. A failed relay coil, burned relay contacts, or damaged feedback circuitry on the board will prevent the Heater Relay Check signal from being sensed, triggering the Hr code.
- 02
Damaged or corroded wiring harness connection at the control board
Wiring / connectionA loose, corroded, or broken connector at the machine control board can interrupt the relay check signal path. Inspect all harness connectors at the board for corrosion, bent pins, or poor seating before condemning the board itself.
- 03
Open or shorted heater circuit wiring
Wiring / connectionWiring between the control board and the heating element assembly can develop opens or shorts, which may prevent proper relay feedback. Inspect the harness along its full run for chafing, heat damage, or breaks.
- 04
Failed heating element
Part replacementA completely open heating element can affect the load seen by the relay circuit and in some board designs contribute to a missing relay check signal. Testing element continuity can rule this out as a contributing factor.
