Whirlpool ADP 6949 C WH Dishwasher: Error F5, Heater Replacement, Service Code 8511 763 10990

Hello everyone,

Dishwasher Whirlpool ADP 6949 C WH model 8511 763 10990 service code.

Last year you came from the service and replaced the heater, then the error Fb (or F6) was displayed, I was laughing that the dishwasher was not connected to the internet and I was hacked by Facebukowcy household appliances. But to the point he replaced the heater but after a few weeks this error again.

He arrived as part of the complaint, replaced the heater, tapped the electronic module with the screwdriver handle (this was to help the transmitter to be stuck together) and announced that the module should be replaced (PLN 500). After timid protests, he said that it would work, but it no longer guarantees the next heater replacement because it is the module's fault. Fortunately, he said which contactor (I exchanged and calm). The whole module 500 contactor 20 PLN. At the same time I asked about this error Fb said that 95% of cases are overdrive (PLN 200). Some rummaging in this forum and someone wrote moisture and rotten microswitch (PLN 2). I had a good few seconds of fun with the soldering iron and again peace for a few months.

But recently, a few days ago, the stairs began:

- F5 error is displayed squeaks and does not wash;
- The NCT sensor is on the network or the washing arms are not rotating (pump, flow sensor);
- Reset, inserted washing and miracle works flawlessly, but only until the next day;
- I disassemble the dishwasher, check the contacts, start the washing pump rotor if it is not blocked, put it together, again a miracle (doing rinsing);
- I start the washing program, the water pump does not start the washing pump (the valve motor can be heard) and F5;
- I dismantle contacts again, OK transitions, I disassembled the OK washing pump, OK pump relay on the module, I assembled;
- Magic completed the rinsing program, activating the ECO program (95% previous use) performs 3/4 of the program and again error F5;
- Mr. on the service, based on the description, says module or pump (I will replace it, but 500 PLN module or 370 PLN pump), and I am no longer strong
- I don't know if more elements will fall
- The pump is EC (electronically commutated) it comes with 230V power supply and three cables from the driver which is on the electronic module controlling the entire dishwasher, from what I noticed in the pump is a pile of electronics including 6 large transistors and a large capacitor and several chips.

I suspect that the contactor feeds to the power supply on the 230V pump, the power supply provides crafted voltages to the coil of the rotor, which gets the voltage decided by the driver on the module and sends control signals to the pump with three cables (maybe variable speed support is even implemented). The pump was manufactured by Blackmann (model VSM E1 SWB).

Advise Ladies and Gentlemen, is it still worth fighting or give yourself a break and look for a new dishwasher? Is aware of the planned aging policy for the product. But if someone can discover a countdown timer in the control module and reset the indication for "first use" then I will gladly use Or maybe it is this power supply at the pump or driver on the module is already falling and you need to replace something. I count on help.

Greetings to all

There is probably too much clearance on the pump impeller, hence its occasional blocking.

Hmmm, I dismantled the entire pump in the rotor part (the electronic part is rather undassembled).
The whole works wet.
There are two hard metal sleeves for bearing there.
They didn't look like they were worn out.
On the rotor and the outer winding, one can see traces of something scratching the surface, but it can be that something has once gotten between and scratched.
Certainly it hasn't ripped off the plastic in which the rotor is flooded.
It turns loose in my hand and nothing scrubs.

Warm, getting warmer

Yesterday I tapped the pump housing with a rubber blunt tool and the entire rinsing program started.
After inserting a full wash, she stood at exactly the same time as a few days ago at 1:10 to the end of the wash and of course F5 error.
Reset tapping again and the entire 40 minutes fast program was painless.
I ordered a new pump. It should be today or Monday.
Swap and let you know if it helped.

Hello,

The pump (new) works but I had to change the O-ring from the old pump.
I translated the O-ring because the one at the pump was old and cracked and, moreover, slightly thinner

Unfortunately, I can't trumpet my success because it comes with strange breaks. As if she would stutter from time to time.
In addition, as I was concerned, I opened the door and closed it again, it did not resume work and error F5 was displayed. What could be the reason ?!?
I'm sure I assembled it correctly.
The only thing that gives me peace of mind is that tapping the turbine brings improvement (means the pump starts) but works very unstable.
Now I removed all possible plastics and gaskets, cleaned from various shavings (although there was not much) and let go with the cleaning agent full cleaning (SOMAT).
If that doesn't help, I'm waiting for suggestions?!?
Greetings to all

Ps Could this be a crazy overload valve? In my opinion, it only directs water to 1 or 2 washing arms (dual zone operation).

What oring and what is it about? What did you combine with the new pump?

For sure? ...

SOMAT did not help
New bank pump (I suspect that storage chair 04.2014 BLDC checked).
There were no signs of use, only this O-ring I suspect that old age had caught up with him.
Sealing O-ring OE 82 mm, between pump motor and turbine.

Hello,

After a short break.
You can say I gave up
It is a pity to invest in "planning an aged product"
After several washes with the turbine tapping - at strategic times of washing - the unstable behavior of the washing pump motor gave way.
I twisted the dishwasher and for now it washes and works, so partial success.
Then the engine "howls" a bit.
But I decided that PLN 200 for the pump motor was the last money I spent on it.
It now works until you "whip" any part and replace it with a new dishwasher.

It is possible that:
- in the controller there is such a program counting the life time (generating random problems later);
- the controller is individually calibrated to the mounted engine (although I do not know what they would be different);
- another power supply was used in the engine electronics;
- the control module has also been damaged (probably only the manufacturer can tell).

Anyway, I'm closing the topic.
Thanks again to my colleagues for help.
