This is one of two dishwashers that I  recently hauled into Canada from Boston.  I always liked the style of these flip-top Frigidaires so when I had the chance to nab one, I didn't hesitate!

It's in good shape overall.  Bonus that I actually like Avocado Green... LOL

I tried it out and noticed right away that the motor seemed to be stuck. So, a little exploratory surgery was in order...

Miraculously, I managed to loosen the shaft upon which the spray arm sits. Better still when I tried powering the dishwasher up, the motor ran in both directions!  I also quickly observed that the timer advances and the heating element works! Wahoo!

However, I want to open up and inspect the pump in case there is any schmutz in there and clean it out.  I noticed a kind of sump cover but I could not remove it.

I also noticed that the wash arm support can be rotated and I wondered if it can be removed so that the sump cover can then be removed.  I noticed a gap in the base of the bracket but I did not try to force it open in any way ('cause we all know my track record for busting obsolete & NLA appliance parts...)

Can this in fact be removed??

Hi Paul, don't take it apart if it works, these pumps usually didn't come apart willingly and you off and ended up destroying parts if you take them apart.

Usually in the field if we had problems with one you replace the whole thing including the motor.

Thanks, John!  At least I asked the question BEFORE breaking the part this time... LOL


Guess I'll be trying a water test this weekend...

Funny, I talked to Paul this afternoon and I guessed that John would say something very similar! I guessed it right! ;-)

Nice find, Paul! I was wondering what the second one looked like. Great find! Cant wait to see more.

I planned to leave myself some play time for the 'new' Frigidaire top-loader this past weekend... And I did!


I figured it would be wise to check the water inlet hose connection (washers do dry up on you...) before hooking it up.  


Surprise!  I found a wiring diagram!


When I first took off that front access panel, I noticed two things right away - the solenoid for the rinse agent dispenser seemed to have been disconnected and there was spare but cut wire on the timer.   Being paranoid, I tested the rinse agent solenoid - it seemed fine.  But that spare wire was a mystery to me...  I checked the wiring diagram and the other side of the terminal feeds the timer motor.  Conclusion? I believe the timer may have been replaced at some point.  Not that I mind - it still works!

I didn't like the look of this, though. 


That hose has a really nasty kink in it and I was worried it bursting when water pressure was applied.


Nope!  So on to the wash test...

So back in with the racks!   They are in amazing condition - nice and soft and not a touch of 'rack-rot'.  


For the test load, I didn't do anything to really challenge the machine - just my newly-acquired set of turquoise-accented Snow White dinnerware that my neighbour bought me for Christmas (hubby got me socks....)


Not exactly a Bob-Load, is it?  I don't think I like the way cups DON'T fit in the upper rack; I remember Jon saying when we checked the machine out at his place back in December that you probably couldn't fit good big wine glasses in there either.  I concur...

I did a short wash cycle - no smoke, no flames, and no leaks!    The sound of water moving around in the machine was impressive and the sides of the cabinet got convincingly warm during the cycle.

I chose not to say 'BUT' - New Year's Resolution.... LOL


However, I noticed a couple of things about this machine that I am not sure about. 


First - that detergent cup...  It seems to trip fine but it looks like it's missing a cover, no?


Second - the timer dial. It's pretty messed up from over-zealous cleaning I guess.  Would this dishwasher have dial selections for a Regular Wash, Short or Utility Wash, Rinse and Dry (or Rinse and Hold), and Plate Warmer?  I thought I could make out at least Regular Wash and Short Wash, but my eyes got sore trying to read the dial....   What does that Rinse and Hold rocker switch do exactly?  Would it shut off the heater unit so that a cycle started at the Rinse spot on the timer dial and then just let dishes drip?


Third - How much water should remain in the tub at the end of the cycle?  I will admit that I manually advanced the timer during the dry cycle and that I did seem to engage a pump-out near the end of the cycle but there was still a considerable amount of water when the timer clicked off.   I started a new cycle and the pump-out phase at the beginning of the cycle drained the tub a lot more!


And would anyone happen to have a cycle chart and operating instructions for a machine of this vintage??


In the meantime I am sure Hubby is going LOVE having a dishwasher in his bar area of the Ogden basement... LOL

Paul, that's what the cycles would be.  It's been 45 years since I opened the user manual in the store for an undercounter Custom Deluxe version of this.  My suggestion is to set the rocker for R&H and start the machine on regular and slowly advance and see if it stops "running" the cycle at the beginning of short wash.  If it doesn't then you R&H by setting the timer dial at Rinse & Dry and it should turn off the heater.
