Bosch stops mid cycle and goes to "Check water supply"?
So my Bosch bench dishwasher has started acting up. It started by going to "Check water supply" light before it even got warm (iv'e later found out that it does warm the water but after it drains this water and applys new water this water is cold, naturally) and used the detergent. I found a video on youtube that fit my issue and did what he did: https://www.youtube.com/watch?v=CIwNv9H3...
After that the machine worked for about two cycles (or one day) and then it stopped working again. But this time it stopps alot later in the cycle. it now warms the water and even start to use the detergent as normal. From start it adds water, does some washing with that water, drain it, adds more water, drain it and then adds water again that it heats up and washes with for about 1 hour. Then just out of the blue it stops and goes to "Check water supply". Its not blinking just constant light. the machine is also nonresponsive and wont do a reset untill i turn it off and on again, start a new cycle and then hold the start button for 3 seconds.
I tried to do the soldering job more thorough just to see if it was a heating problem like in the video so i basically just scrapet off more of the green masking and made the soldering longer and even touch one of the metal holes further up on the PCB (since its all connected to the same metal plate under the masking). but it doesnt help. When it stops ive waited for about 12 hours and nothing happens.
Iv'e also tested diffrent types of water hardness on both Water softening for Special salt and Rinse aid with no luck.
Last night i tried water softness on rinse by telling the machine its not as hard (set it from 2 to 1) and then the water seemed to get too much. It went past the filter ring. I then tried to set it to 3 and same thing happened. Set it back to 2 and still same thing. See last picture.
Ill add some pictures of everything.
This is the machine i have:
Also ive checked the water cable and the draining cable and its all good. Ive also checked the drainage pump and cleaned the filters and checked the spray arm.***
Ive also tried to turn off the drying cycle and ive tried washing on a lower degree celcius program (40 degree celcius) and nothing helps.
So i went on another round of soldering. this time i also resoldered some of the filled in holes just north of the big solder on the pic i posted, the one on the top alittle to the right. i also removed the metall on the sides/top just to have a look. and i took of the white styrofoam and pressed teh drainage button about ten times.
What actually fixed my problem is unclear, but it work again! Im pritty sure it was the soldering that fixed it, either the big one resoldered and cleaned up properly, and/or the holes i resoldered at the top (I pritty much just heated the holes up again and let it cool back down). the holes is attatched to one of the two big white blocks on the other side of the pcb (actually through the whole PCB there is 5 off theese, two close to eachother and 3 abit further away). the blocks have the following markings:
HF3FD 012-ZTF(576) 10A 250WAC 85*C China DP078B
Since the button behind the styrofoam is the drain water fail safe, and draining the water was never a problem then i dont think that was the fix.
It has now stopped working again and now it again stops at "Water in - Wash and heat the water - Drain water - Water in (stops right at the end at the water intake. It stops and goes to Check watersupply while water is going in, just at the end when machine is full off water)" like it did in the beginning of the problem.
So new theory here. Maybe everythime i drain the machine compleetly of water (except the special salt compartment) somehow this makes the machine work for a about a day? maybe the soldering im doing does nothing? i just think it does? i tried to remove the pcb without removing the water intake and water drainage hose'es and redoo the soldering on the pcb then put it back together again and this did nothing. but the other times ive tried (and the machine works then for a day or two) ive reomved the hose'es and put the machin up on its side in order to access the underside of the machine. This way the water left inside the machine (after a drain cycle) pours out of the drainage hole where the drainage hose would be attatched. I feel like ive checked most of the other stuff on the machine now, even the connector on the heating pump and it all looks normal, all tho the connector on the heatingpump is abit burnt (the metal part, not the plastic), but not much.
I just tried the old way where i disconnected it and drained the machine, redid the soldering again by removing the old solder as good as i could and reapplied new. it still crashes...
Tested a 40 and 50 degree program now and now it works :S i bet as before it will work for about 2-4 washes or 1-2 days and then stop working again >.<
Here are the 4 types of crashes it gets. What ever type its at it will always be like this untill i drain the machine, take it out of its place and disconnect everything, open it up and remove the main PCB and do so soldering on it then put it back together. After i do that it might change or it might work for a couple of runs then suddently it will choose one of theese 4 types and stay on that type.
1: Water in - washy washy for about 15-20 minutes where it also heats the water - Drain the water - Add new water then crash as the last of the water goes in.
2: Water in - Washy washy with warming the water - Drain - Water in (to clean off any residue at the floor of the machine) - Drain water - Water in - Washy Washy with heating water for abit then open detergent door and wash for a little while more then boom crash with hot water still inside.
3: Water in - Washy washy with warming the water - Drain - Water in (to clean off any residue at the floor of the machine) - Drain water - Water in - Washy Washy with heating water for abit then open detergent door while it keeps washing - Drain water - Add water (To clean off any leftover detergent on the floor of the machine) and boom crash while water is close to end of adding.
4: Water in - Washy washy with warming the water - Drain - Water in (to clean off any residue at the floor of the machine) - Drain water - Water in - Washy Washy with heating water for abit then open detergent door while it keeps washing for a whole cycle - Drain water - Add water (To clean off any leftover detergent on the floor of the machine) - Drain water - Add water washy washy - drain water - add water (to get ready for last washy washy and drying program) and then boom crash while last part off water comes in.
Is dit een goede vraag?
