I have successfully used a D1NA60 FET from an earlier version (phase 5) controller to replce the D2NC60. It is a lower rated component but it works. It was necessary to replace the cold solenoid valve (had gone low in resistance to 15 ohms) and the on-board wired fuse as well but all works OK.
A higher rated FET which could be substituted is ST D5NM60.

Fault 49 pops up on the screen


If your washer is a Fisher Paykel Top-Load Washer Error Codes = 49 I found this online by typing "Washing Machine Fault 49" into a google search engine...

Error Fault Condition - Water Inlet Valve Fault.
Repair or Check - Unplug the washer from power. Reconnect any non secure wires on the water inlet valve. Replace the wire harness if it is found to be damaged. If the wiring is okay then measure the resistance of the water inlet valves using an ohm meter. If the resistance of each water inlet valve solenoid is not 60 to 62 ohms then replace the complete water inlet valve assembly.
Parts for Replacement - Water Inlet Valve Assembly or Wire Harness.

Fisher & Paykel WL26CW1 - Error Code 49! can i swap the hot and cold valves to make it work and disconect the hot valve?? and love this site very informative, Thanx Guys..


The most common problem with AquaSmart is the pump
not the water valves
The pump has gone bad and blown some parts in the motor controller board and the fuse to the water valves.
Some AquaSmart machines display the wrong Error code (49)
witch is not the correct code for this problem.
Pump and motor controller board need replacing.
Maybe cheaper to buy a good secondhand machine.

Washer gw712 diagnostic lights3rd from left and forth from left on and last on right


That is fault code 49
49. (00110001) Cold Valve or Cold Valve & Hot Valve Faulty
The Motor Control Module has measured a voltage from the valve diagnostic circuit that
indicates the cold valve or both the cold and hot valve is faulty. The most likely cause is
that the valve harness has not been connected correctly or the valve(s) is open circuit.
Primary Source: Wiring.
Action: Check the valve harnesses are correctly fastened to the valves and
the motor control module or the pins are not bent backwards.
Secondary Source: Water Valves.
Action: Measure the resistance of the cold and hot valve coils.
Tertiary Source: Motor Control module.
Action: Replace the Motor Control module.

Fisher & Paykel washer GW712 won't spin


There is an issue with your drainage area. Best to remove the pump and check for the obstruction in the line or at the impellar.(If the water is not completely drained, the pressure switch wont send a low level to the timer to allow a spin).

Washing Machine won't work


Sounds like error 49.
A water solenoid. I bought mine for $40 on ebay. FP didn't want to help. I still had the same problem after so I did a bit of chasing. I wasn't going to pay $350 for a controller, they must cost about $30 to make!

If you look closely at the solenoids you may see a bulge or burning.



I replaced the solenoid but still had binary 49 LED code. I chased the circuit through the Motor Controller (brown one in Australia) GW712.

It was a couple of FETS or Qs in a H drive. The get fed their +v from the main power rectifier. There is a funny looking round component called F^ which is a quick blow 1.6 A fuse. Because my solenoid had a shorted turn on it (bubling to outside packaging) it had blown this.

I didn't have one instock so I substituted an ordinary glass 2AG 2.0amp fast blow. You need to remove the old fuse and solder 2 wires into the holes left these are inturn soldered to the fuse ends. I used hot glue to hold the fuse clear of any other components.

You can get slow blow fuses almost anywhere. In my experience ordinary fuses are the same they always fail after the components are lost anyhow!

If you are desperately dirty you could just jump the 2 holes with tinned copper but this could represent a fire hazard if a solenoid goes again.

We amke microcontrollers. It is a simple fix and saved me $350. A fuse is 10c or maybe $1 if you buy them one at a time. Make sure you test the plugs before you start up. My GW712 read:

1. Each motor winding ~ 35 ohms to any other
2. The lid solenoid ~ 70 ohms
3. Each water solenoid ~ 60 ohms
4.The thermistor ~ 10K ohms


# When this fault exists you can empty the water by removing the tube to the Pressure Xducer and using a tube from your mouth to blow into it HARD!!! The pump will start and pump it out for you.

To calculate the error code (for what use that is when you can find out)
