Fisher & Paykel Washers 30 Error: Water valve fault
Fisher & Paykel washer error code 30 is a mid-severity fault meaning Water inlet valve fault — fill not completing. If code 30 clears after cleaning the inlet screens or confirming the supply tap is open, the machine is safe to use. Power-cycling clears the fault.

Answer to continue safely
Is it safe to keep using?
Maybe. If code 30 clears after cleaning the inlet screens or confirming the supply tap is open, the machine is safe to use. If the inlet valve solenoid has failed, washing should be suspended until the part is replaced to avoid repeated fault cycles.
Can I reset the code?
Yes. Power-cycling clears the fault. If the code reappears at the fill stage of the next cycle, the root cause (blocked screen, low pressure, or failed valve) has not been addressed.
When to stop immediately?
Stop if you notice: No water enters the drum despite supply taps being fully open and hoses being unkkinked, Water leaks from the inlet hose connections after cleaning the screens.
Symptoms You May Notice
Code 30 displayed after fill phase
The machine fills for the maximum allowed time, fails to reach the required water level, and raises code 30.
Drum fills very slowly or not at all
Water trickles into the drum at a much lower rate than normal, or no water enters despite the fill valve being energised.
Cycle pauses at fill stage
Progress through the wash programme stops at the beginning of the wash or rinse fill, with the display showing the fault.
Possible Causes
Kinked or closed water supply hose
The inlet hose to the machine is kinked, partially closed, or the tap supplying it has been turned off, restricting water flow.
DIY PossibleClogged inlet valve filter screen
The small mesh filter screens at the back of the machine where the inlet hoses connect have become blocked with sediment or mineral deposits.
DIY PossibleFailed water inlet valve solenoid
One or both solenoid coils in the dual inlet valve assembly have failed, preventing the valve from opening on command.
DIY PossibleLow water pressure
House water pressure is below the minimum required (typically 30 kPa / 4.4 psi) and the valve cannot achieve adequate flow.
DIY PossibleSafe Checks You Can Do
-
1
Check water supply taps & hoses
Confirm both hot and cold supply taps behind the machine are fully open. Check the inlet hoses for kinks along their full length.
It is common for the tap to be left partially closed after maintenance work on nearby plumbing.
-
2
Clean the inlet filter screens
Turn off water supply taps, disconnect the inlet hoses from the back of the machine, and remove the small mesh filter screens with needle-nose pliers. Rinse under running water and reinstall.
Even a partially blocked screen reduces flow enough to trigger code 30. This is a free fix that resolves a large proportion of fill faults.
Tools required -
3
Test water pressure
Fill a 10-litre bucket from the supply tap that feeds the washer and time how long it takes. At adequate pressure, 10 litres should fill in under 60 seconds.
If pressure is marginal, run the washer without other water-using appliances active.
-
4
Test the inlet valve solenoid
With the machine unplugged, disconnect the solenoid wires and measure resistance across each coil. A healthy solenoid typically reads 200–500 ohms; open circuit indicates failure.
Inlet valves are relatively inexpensive components and are straightforward to replace on SmartDrive top-loaders.

When to Call a Professional
Contact a qualified technician if:
- Solenoid tests faulty and you are not comfortable replacing a water valve on a plumbed appliance
- Low house water pressure — a plumber rather than an appliance technician is needed
