Fisher Paykel GWL11 -- New Diverter Pump Not Operating

10 posts in this topic

My GWL11 went dead the other day, so I got a new control board and revived it.  However, the diverter valve was not operational.  Being a common problem, I replaced that as well, but even the new valve is not operational (I ran the test from the GWL10 manual).  Impedance on the valve checks out.  This points to either the control board being broken out-of-the-box or a wiring fault. 

 

The replacement control board was not exactly the same as the old one.  Specifically the diverter circuit was connected via a pig-tail across the module.  Even so, there's no "wrong" way to plug these wires in.

 

What voltage should I expect into the diverter valve circuit while it is activated?  

 

Thanks for the info!

The perverter valve is just a wax motor with a flapper.  The wax motor in the perverter runs off 120vac that it gets from the control board.  Can check for this voltage at the control board.  

 

Did you buy a new control board from F-P or a used on on that freakin' auction site?

Thanks for the quick reply!

 

The board is only putting out ~14Vac when the valve circuit is enabled via the diagnostic panel, so that sounds the culprit.

I got the board from "letstalkparts.com" -- looked new but might have been a refurb.  Doubt FP is making this part anymore.

i guess we'll see how their customer service is now.

 

If this all goes south and I have to buy a new washer, what's your recommendation?

Front load LG washers are the best on the market at this time. But, if you liked the FP, there is no reason not to get a new one.

Thanks for the advice.  The FP is 10 years old and came with the house so I'm not overly attached to it.  

I just hate throwing out stuff that's not broken.

Try this:

 

Unplug the diverter connections at the valve and test for 115 across the wires with the diverter out of the circuit.

 

You say the valve coils check out for resistance, what did you get? 1.2k to 3.6k or something in that ballpark or did you get a lot less?

 

As a former F&P warranty tech I can't advise strongly enough that you pull the hoses and triple check that a bobby pin wasn't hiding in a hose and then slip down into there after you installed the new valve. It never takes much to jam them... a quarter, bobby pin or safety pin is all it takes and if one was still in the hoses when you swapped valves.... yea.

 

Also, those F&P's are almost always worth fixing. Odd thing is that bad main bearings and main lip seal is one of the cheapest fixes in the whole machine (under $20 for parts). No transmission, clutch or brake to go bad either.

 

They're an odd design and have their weak points, but they have strong points no one else can match too.

Did you properly configure the new board to the rest of the machine. You don't just swap controls on a FP, there is a specific sequence to configure the new board to match your washer. The instructions would have come with the new board. And Vets is right, double check for diverter valve obstruction.

I was getting around 2.6k resistance at the wiring harness at around 68F.  Voltage off the board was only 14Vac when energized.

 

My wife mentioned this morning that she heard a 'pop' at some point during the first load, so I'm pretty convinced the mosfet went.  Question is... why?  Had to be a short somewhere, so maybe I test for continuity between the wiring harness connector and cabinet ground (ie. frayed wire)?  The valve-side connection is well protected from leaks.  Is it worth putting a fuse on that line?

 

@nick:  I did size the machine after installation following the instructions, and double checked it.  PermPress loads wash just fine.

Final update:

I got a replacement board from LetsTalkParts at no cost and everything works perfectly now. I added a 250mA fuse on the diverter circuit just in case whatever happened this time happens again.

 

Thanks to everyone here for their help and suggestions.  Beer money is en route.

Domo for letting us know how it turned out!
