Re: Dead F&P GW703

After purchasing and installing a used display module from EBay, the machine then came to life. I did notice the controller is for a MW series 3 not a GW, not sure what implications this has if any.
After I reset the display module, things appeared more hopeful although the machine exhibited some strange behaviour.
No matter what part of the cycle it was in, it would cycle it at intervals of a couple of seconds on, then a couple of seconds off continuously.
Eg, if it was filling, it would cycle the solenoid(s) on and off every few seconds, and the same for the pump if it was meant to be pumping.
I’ve read another couple of threads on here about similar behaviour with other machines but there were no solutions to this that I could find.
Perhaps this is the result of putting a MW series controller on a GW series machine, I don’t know. I thought the MW just had a few less features.
When put into diagnostic mode, the pump and solenoids operated normally.

Anyway, as it turns out I salvaged a display module and motor controller from a GW601 before my neighbour threw it out.
I installed both these components after a small modification to the display module to make it fit and a piece of tape to activate the micro-switch. At last the machine now appears to function normally.

After all this, does anybody know what functional differences are between a GW701 and GW703 as I guess it’s now turned into a GW701.

Also, does anybody know if a series 3 MW controller will operate normally in a GW703 machine?
I’m just wondering if either the motor controller or the display module, both of which were purchased second hand but supposedly good, might have a fault.

Re: Dead F&P GW703

Ok, I’ve measured the RPS voltage of a working GW703 and it was 10.88V with the RPS plugged in, this went up to 15.80 when I unplugged it.
Seems this voltage on the dead one looks ok, so at this point it wouldn’t suggest the RPS needs replacing.
In light of this I’ll purchase a replacement display module and see how things go.

Re: Dead F&P GW703

Hi, I’m located in the NE suburbs of Melbourne, Aus, where are you ?
I have a friend who I’ve discovered has the same/similar machine.
They have agreed to let me check the RPS voltage this weekend.
Will post back with the results.

Re: Dead F&P GW703

Ok, perhaps there was a little too much info in my original post.

Can anybody confirm the 15.5V supply to the RPS is meant to actually be 15.5V when the RPS is plugged in ?
Mine is currently sitting at 10.86V when the RPS is plugged in and goes to 15.78V when it is unplugged.
