Fisher & Paykel EcoSmart Code 48: hot and cold valve coils not responding

What 48 means

On Fisher & Paykel AquaSmart and EcoSmart top-load washers such as the WA37T26EW and WA42T26GW, and on SmartDrive Phase 2 to 6 washers like the GWL15, code 48 means the Motor Controller Module has measured voltages from the valve diagnostic circuit that show both the hot and cold valves as failed. The most likely cause is wiring that is not connected correctly or a valve that is open circuit. The washer stops filling.

Common causes of 48

Both valve harnesses not connected correctly
Valve open circuit
Control not reading the valve circuit

✓ One safe check you can try

1. Unplug the washer. 2. Check that both faucets are open and the hoses are not kinked. 3. Plug in and start a short cycle, watching whether any water enters. 4. If 48 returns, stop and call us.

! Why to stop there

Two valves reading wrong at once suggests the shared wiring or control, not two parts
Guessing at the valve wastes money
We find the cause and give a written price first

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Why do both valves show up at once?

When both read wrong, the shared harness or the control is more likely than two valve coils failing at the same time.

How is 48 different from 49 and 50?

49 means only the cold valve reads wrong; 50 means only the hot valve does. 48 is both.

Can I run cold only?

If both fail, no water enters, so there is nothing to run until it is fixed.
