Whirlpool VMW Speed sensor intermittent failure

Posted by Applianceman97, 04 December 2014 · 212 views
VMW, Whirlpool, WTW

Hi Boys and Girls,

So we all have seen the basket speed sensor fault on the VMW washer's right??? Well I had one with that fault code but i could not produce the problem at time of servicing the machine. All functions tested good. Tach verification mode passed. EVERYTHING checked good. Ran rinse and spin loads, seriously... the machine worked perfect!

Well long story short, got a call back the NEXT day. Complaint was no spin again. Got there and did all my testing and AGAIN everything checked good.

Then I had the customer load the machine with a load and ran a rinse and spin cycle. Guess what it ran FINE! It took 3 rinse and spin cycles until the fault showed up again. Sure enough it was the basket speed sensor fault. I quickly went to the tach verification mode and the test failed. Intermittent actuator (well optic sensor) failure.

So double and triple check your optic sensors folks. They can fail intermittently!!!

Whirlpool GWS Dishwasher pump hose slips off sump

Posted by Applianceman97, 04 December 2014 · 161 views
Whirlpool, Global wash system and 2 more...

Whirlpool Dishwasher (GWS Style)
Mod# GU3600XTVQ1
Ser# FY3401292 (Manufactured 8/2009 - must be one of the first of these out, I thought they started in 2010).

Main pump hose, (has those funky machine squeezed clamps), slipped off sump connection. I replaced with good real hose clamp, one month later it has slipped off again.

I did extensive searching in here because I thought I had read an earlier account of someone else having this problem and some kind of recall on this but the only thing I could find was this tech bulletin W10547922


Samurai posted the above after I asked more about it when it was discussed in another thread but it only purtains to a few models/stainless units manufactured in 2012 and only references a $8-$12 single hose clamp, basically what I already tried.

I looked up the hoses/clamps for this unit and it comes back as an expensive kit with both inlet/outlet pump hoses, new rubber rear motor mount and 5 really good hose clamps - it appears you would use two of the clamps on the end of the hose that slips off the sump.

Here is the new hose and clamp kit:
Part number: W10168824

Part number: W10168824

Anyone have access to Service Matters to see if this kit has an instruction sheet that comes with it and/or know of any tech bulletins purtaining to this problem in the early models of the GWS dishwashers?

Is this going to fix the problem of the hose slipping off and flooding the kitchen?

Great info from brother Budget! Thanks Brother!!!

Whirlpool Duet Sport/Kenmore HE2 CCU revision WRONG!

Posted by Applianceman97, 21 November 2014 · 254 views

I recently went out on a repair where the customer had already attempted to fix his machine (ugh, we know all know how that goes. Anyway, he had diagnosed the problem to be his CCU and ordered the part himself and installed. After installation his main error he was receiving was fixed but the display was not correct. The display showed 37 minutes for all cycles except Whitest Whites and Clean cycle. They just showed - - (double dashes). Because I got thrown into this repair late I kinda got screwed. With the new CCU installed I figured it was good since it was new so i Completely unloaded the CCU. Only had Power input to the board and my UI connected. Still got the same display. This told me we had a bad UI. Ordered new UI.

Received new UI and went out to install it and when i did i received the same problem. I had another CCU and i installed it as well and STILL got the same display problem. 37 minutes and double dashes. So lets recap here. 2 new CCU's and a Display board and the problem is still there. THERE IS NOTHING ELSE TO CAUSE THIS PROBLEM!!!. I was pissed to say the least.

SO I called my parts supplier and we did some digging together and found that he still had the old version of this CCU still in stock. So I got that one, went out to the customers home and installed it and THAT FIXED IT!

Are you kidding me????? Dumb ass Whirlpool can't make the right part for their own machines.

SO here you go. So far the affected models I know about are

110.47531701 (Brother ToneBlair found this one)

I will keep adding models and feel free to comment models you find as well.

Whirlpool Coin Op VMW Washer Model drain pump runs and runs even after unplugging.

Posted by Applianceman97, 30 October 2014 · 264 views

I couldn't find this issue in the archives. The lid is locked, light on solid. It continues to run the drain pump even after unplugging and plugging back in. I cannot enter the diagnostic mode. The green light on the control board is on. I lifted the top and noticed the clothes in the washer were dry and loose so this problem must have occurred before the washer filled.

Info from Brother Adirondack Bob,

Per Tech Line from a call I had a couple months ago-

Voltage to the washer was lost for whatever reason.

When power is re-applied the Drain Pump will run for 6-9 minutes.

If washer is unplugged and plugged back in, pump will start over and run for 6-9 minutes again.

Solution is to let pump run until it shuts off on its own.

Odd finding when working on a frigidaire range

Went to work on a frigidaire built kemore range with a no DOA complaint and here's what i found.

Frigidaire front load boot replacement.

Cast iron pan oven calibration

Posted by Applianceman97, 19 June 2014 · 714 views

Sorry everyone, held my phone in the wrong direction

Here is a different way of calibrating an oven. The cast iron pan measures the cooking temperature in the oven cavity. There much less swing in temperature by using this method than a standard thermocouple. One thing you cant tell from the thermocouple is how long your oven stays at the min and max temperature. While using the cast iron pan method you KNOW what temperature the oven is cooking at.

The reason a cast iron pan is used in this method is because the mass of the the cast iron and the unreflective surface will give an accurate reading from the IR gun. You can't use an IR gun inside the oven cavity without the cast iron because the thin reflective metal will always read incorrect. You have to have the non reflective dense cast iron pan.

THis particular oven cycle at these temps (after calibration)
Thermocouple ranged from roughly 340 degrees to 395 degrees.
Cast iron pan temperatures read (done throughout cycling) 343,359,356 and the highest reading at the top of the cycle was just under 380. Its much easier to get the average temp of the cast iron pan vs the thermocouple.

Whirlpool VMW Washer F7E5 drive system error.

Posted by Applianceman97, 16 June 2014 · 840 views
VMW, Whirlpool, Drive Error, F7E5
By now most of us have encountered the F7 E5 error on the whirlpool VMW washers. But here's a blog on it anyway.

This is a drive motor error. When the machine is started the sensing part of the load starts and usually when this error is present the machine will shut down after a few seconds and the lid lock light starts flashing. This means the main board is not sensing the rotation of the basket correctly or not sensing basket movement at all.

First step in diagnosing this problem is making sure the basket turns free and is not jammed in any way. Then check for correct voltages at the main board (have yet to change a main board for this issue some techs skip this step and move straight to the shift actuator.) This is issue can also be caused by an optic sensor falure. The optic sensor is inside the shifter assy. You will the replace the whole shifter assy to fix the optic sensor failure. In my experience the optic sensor is usually the cause of this error. There is an optic sensor test you can access and by spinning the basket by hand the lights on the control will dance showing the optic sensor is reading movement. The exact procedure is in the tech manual.

The shifter is not always the cause of this error though. Remember that VMW's just point you close to the problem not leading you directly to the part failure so always check main board connections and wire connections at motor and shifter assy. Also check the red coil of wire on the bottom of the tub for a broken wire.

There has been one case that i have heard (from Kurtiusinterupptus) that the drive block was the cause of this fault. The machine would start to run and just shut down and the lid lock light would flash just like when a shifter fails. After 2 shifter replacements (thought one was bad out of the box) Whirlpool tech line help (didn't help much) and much frustration brother Kurtius got it whipped.

If your battling an F7E5 error make sure you are armed with a shift actuator. This will be your most common replacement. Also be aware of the drive block problem. The drive block failure has not been common in these machines but im sure more will come. So be aware the drive block can cause the error as well as the other listed components in the tech manual.

Also check to make sure the transmission drive pulley is not loose/broken. This problem could also occur when there is a stripped splutch. Capacitor could also cause a motor error.

Here is a list of common VMW parts that are failing. Some cause the drive error, some do not.Common
