Further tests of the 'new' Frigidaire dishwasher

I've been in St-Lib this week so I thought I'd do some further tinkering with my new toy, that 78 Frigidaire Imperial dishwasher. 

My first goal was to try to find where the drip I had observed in the first 2 tests might be coming from. I set the machine up on a couple of boards to see if I could observe anything, with the help of my phone camera.  I ran it through a full 'pots and pans' cycle.  Amazingly, no drips or drops were observed! Perhaps the dribbles were due to a dried up seal somewhere... I was pretty happy needless to say.

Congratulations Paul!!!

However....

Yes there always seems to be a catch with my vintage goodies...  I had selected the 'Extra Hot Wash Temp' option to see how it behaved in a full cycle test.  The timer paused and the dishwasher heated up the water - 'cept it didn't seem to want to stop heating...  

I stopped the machine after 30 minutes and hit the off button for the Extra Hot Wash option. The timer started up again and drained, like what happened in a previous test. But that water was hot!!  Hotter than the James Sweepflow claim of being able to sterilize labware.

So after the cycle ended I thought I had a problem with a high-limit thermostat (like that built-in Kenmore Roto-Rack did).  Trouble is, I didn't see a thermostat in the wash tub.

Would there have been one or just some kind of a cycle extender switch?

I am eagerly searching for some service literature for this dishwasher...

Oh, Phil???

Check the wiring diagram for a thermostat?

 

[turquoisedude]

I don't have one.... I'm going to crack the door panel to see if there may be something tucked in to the timer box like the good folks at Maytag used to do.

Thermo

I think it’s on the inner door panel. I’ll check the manual for sure tomorrow

 

[steved]

Nope

Sorry I’m wrong. It’s on the tub bottom near the pump. Plus here’s a schematic

 

[turquoisedude]

Thank you Steve!!  I didn't do any further exploration on the dishwasher yesterday - I was called to help clear out a friend's mother's house following her move to a senior's residence.  49 years worth of stuff accumulated and I took one carload so far.... LOL 

 

[philr]

It was in the inner door panel on the earlier metal door models like my 1969. Mine also took forever to heat up the water. I tried that feature just once! But eventually it did reach the temperature and the timer resumed.

took forever to heat up the water

With such an extended detergent wash, imagine the possibilities of downright grimy BobLoads you could challenge that dishwasher with. To me, that's a lot of the fun--see just how much I can get in there as well as will it all come clean.  Man against machine!!!

 

[pulltostart]

Uh-Oh

I sense the birth of a new term!

 

When the dishwasher is not only PACKED, but you're dealing with (in Bob's own words) "grimy" dishes - what are you dealing with?

 

Why, a BobJob, of course!

Lawrence, hilarious!!!  Reminds me of the cleaner Top Job. 

 

[jetcone]

Well

I do know of an Elite Model that was made in Poppy.......Its not Imperial nor Custom Imperial so no aberration there!!

I'm in St-Lib today, so naturally I am messing with the "new" Frigidaire dishwasher instead of doing anything practical like housework, yardwork, or laundry... LOL 

Thanks to Steve's info, I located and extracted the water temp hi-limit thermostat. I don't have the original Frigidaire part number but I think (bad things can happen when I do that...LOL) the thermostat is a Therm-O-Disc 36TR12.

Amazingly, I am finding similar items but I am getting confused with the specs for the newer ones.

It seems they are made by Emerson now and the suggested application is in a pellet stove; high limit seems to be 120 degrees Fahrenheit.  I have seen others for dishwashers with a 200 degree cut-off.

Has anyone here replaced an old dishwasher thermostat recently and if so, what did you use?

 

[turquoisedude]

As the thermostat was out, PhilR suggested I test it.  It's not elegant, but I heated water and dipped the thermostat into the hot water and checked with the VOM.  I got it to work, but I didn't know just how hot the water was.  Meanwhile, SteveD in Guilderland suggested cleaning the spot where the thermostat contacts the tub. I did and then re-installed the thermostat.

So, looks like I am going to have to haul this one into the kitchen for a real test...LOL    Any howls you heard won't be from Canyon!

 

[cuffs054]

Paul, could you redo your test and use a candy thermo to test the opening temp?

 

[philr]

Tom has a great suggestion!

 

[jeff_adelphi]

Looks like your thermostat has F145 stamped on it, 145 would be the temp, and the F is for "fan",  this thermostat's contacts close when the temp is reached.  Many of these thermostats have an L for limit on them, on those the contacts open when the temp is reached. It's a fairly common thermostat used in many heaters and small appliances.

 

[cuffs054]

Paul, have you given up on this great DW?

 

[turquoisedude]

Certainly not!  I finally remembered to bring my candy thermometer from the kitchen in Ogden back to the house in St-Lib so I can test that thermostat again.  I'm actually itching to try this machine out with a true BobLoad!!

 

[appnut]

Oh my!!!!

 

[potatochips]

I had the same issue with a Whirlpool machine and the thermostat. I ended up setting my meter on continuity, and blowing a hair dryer on the thermostat with a meat thermometer stuck on the stat, I had a few of them and it seems the ones set to 140F usually close contact at 120F or so.
