Fisher & Paykel Washer Error Code HOT flashing

The HOT flashing error means the washer has detected a problem with its hot water supply. The machine expected to receive hot water for the selected cycle but either received none, received water at too low a temperature, or detected restricted flow. Common causes include a closed hot water faucet, clogged inlet screens, reversed hose connections, or insufficient water heater output.

The washer halts the cycle when the HOT error appears, so it will not continue operating in an unsafe condition. You should not attempt to force the cycle to continue without resolving the underlying water supply issue, as this could result in improper washing results or repeated fault conditions. Address the cause of the error before restarting the machine.

If the fix involves simply opening a closed faucet, reversing hose connections, or cleaning the inlet screens, there is no parts cost involved and you can resolve it yourself at no charge. If the hot water inlet hose needs replacement, hoses typically cost in the range of $15 to $40 depending on the model. If a technician visit is needed to diagnose or replace a faulty water inlet valve, service call and parts costs could range from $100 to $250 or more depending on your location and the specific parts required.

Start by confirming the hot water faucet behind the machine is fully open. Next, check that the hot and cold inlet hoses are connected to their correct ports on both the wall and the machine. If those steps check out, remove the hot water hose from the machine inlet and inspect the small mesh screen for sediment or scale buildup, cleaning it with a brush under running water. Finally, verify that your water heater is set to an adequate temperature and has not been recently depleted.

A reset may clear the flashing indicator temporarily, but the error will return if the underlying hot water supply problem has not been corrected. Resolve the root cause first, such as opening the hot faucet or clearing clogged inlet screens, and then restart the cycle. The machine should proceed normally once it confirms adequate hot water delivery.
