American Water Heater HPE10280H045DV, HPE10260H045DV manual Fault Code Troubleshooting Guide

Fault Code Troubleshooting Guide

Upper Element Connect Fault (Upper heating element circuit is open):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box and check for a loose connection at the element. For access directions see “Heating Element Replacement” (p.24).

Upper element faulty-

•Check resistance of the element itself to see if it’s around 12.4 Ω. If it is broken, replace non- functioning element. See “Heating Element Replacement” (p.24).

Control board faulty-

•If the error persist, the problem may be caused by the control. Replace the control board.

•If replacing the control board doesn’t resolve the issue, contact technical support.

Lower Element Connect Fault (lower heating element circuit is open):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box and check for a loose connection at the element. For access directions see “Heating Element Replacement” (p.24).

Lower element faulty-

•Check resistance of the element itself to see if it is around 28 Ω. If it is broken , replace non- functioning element. See “Heating Element Replacement” (p.24).

Important: Using an element greater than 2000 watts in place of the lower element will damage the water heater and void the warranty.

Control board faulty-

•If the error still persists, this problem may be caused by the control board. Replace the control board.

Heat Pump Connect Fault (Heat pump compressor circuit is open):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box.

•Check wire harness connections at compressor, control board, run capacitor and compressor relay.

•Inspect wires for damage.

Compressor thermal protector open-

•Compressor will restart after coolling off. Faulty run capacitor-

•Check the capacitor, see “Checking the Run Capacitor” (p.26), replace if defective. Control board faulty-

•Replace control board.

•If replacing the control board doesn’t resolve the issue, contact technical support. Compressor faulty-

•Check the compressor, refer to the “Checking the compressor” flowchart p.28, replace if defective.

Fan Connect Fault (Heat pump fan circuit is open):

Loose connection or damaged wire-

•Turn off power at the circuit breaker / fuse box

•Check that connector CN207 on control board is seated.

•Check wires for damage

The internal protector of fan motor may be open or the fan motor is broken-

•Check the fan motor, refer to “Checking the fan motor” flowcharts (p.30-31). Replace if defective. Control board faulty-

•Replace control board.

•If replacing the control board doesn’t resolve the issue, contact technical support.
