Fisher & Paykel DD602 -- upper drawer has no power

6 posts in this topic

A rodent ate through the water supply to my upper DD. While awaiting the replacement hose, I plugged the old hose and unplugged the wires going to the valve that diverts water to the upper DD. 

 

 I finally received the replacement hose and replaced it.  Installation seemed to go fine.  Had to remove the front cover (I did remember to reconnect the ground wire on the cover) to do so.  Reinstalled, plugged the connecter back into the diverter valve.  Reset the circuit breaker.  No workee.  I get no power indication at the display at all.

 

Lower unit continues to work fine.  When I switch the breaker on, the display turns green, there's an audible beep, etc., on the lower unit.  But nothing on the upper.  Zero.  Zilch.

 

Is there something obvious I've overlooked?  Do you have any suggestions for troubleshooting to narrow down the location of the problem?

 

Thanks,

Sounds like one of the wire harness connectors on the control board isn't snapped in all the way.  Disconnect and reconnect 'em all.

Fisher Paykel DD602 dishdrawer with the front panel removed.

Check for 120v supply going into the the main control board.

Also check the wiring loom to the top drawer from the mains board up, as the mouse may have had a go at this when he did the water hose (:shock:seen it a hundred times...................).

I have disconnected and reconnected all of the connections.  Also checked the wiring harness to make sure the rodent hadn't chewed threw it.  Still no power to the unit.

 

You mentioned checking the 120 volt to the main control board.  Are you talking about the board on the bottom of the lower unit, or are you referring to the control board behind the front panel?  In either case, is there an "obvious" spot to check it?

 

Thanks,

Click the photo in my previous post for the larger view.  You'll see three wire harness connectors along the bottom of the control board.  One of them supplies line voltage.  Gaze lovingly upon the inscriptions just above the wire harness connectors (on your own dishdrawer) and the line voltage location shall be revealed unto thee.  Cro Maat.

I had a similar problem with my lower drawer, completely dead. Found that the solder fuse in the heating element had blown. For some reason this causes the whole unit to power down
