Re: Baumatic BDF 683 SS Locking up

I cannot afford to bin a dishwasher just because there are better ones around. My time is my own and I cannot afford to buy a new one.

I have run the test cycle,I’d like to upload a scan of the instructions, but don’t know how or if I can on this forum (I don’t use photo bucket etc) so here is an abridged version:

To enter test mode:

Open door, press and hold “Rapid Prog” (far RH button) and turn on machine. Close door.

Initialization Display = 8.88 Turned on and ready

Water Inlet Display = 0A Valve open,3.6l of water (confirmed by water meter on my water softener)

Dispenser Display = 09 Wash pump and Dispenser on for 1min

Heating element Display = 08 Wash pump & heating element on until 60DegC

At this point you have to press “Rapid Prog” to advance to the next step (more of this later)

Drainage Display = 07 Drain pump for 1min

Pauses Display = 06 Pause for 15 secs

Inlet Valve Display = 05 3.6l of water (if your model has a fan it is tested here, if not Display = 99

Wash Pump Display = 04 Wash pump on for 3min.

1/2 Load valve Display = 03 Wash pump off 1/2 load valve for 3mins

Wash pump & 1/2 load valve Display = 02 as it says for 3 mins

Regen valve and drain pump Display = 01 as it says for 1min.

EOT Display = F0 End Of Test.

So all that passed the test, so I have made some assumptions (tell me if you think they are wrong and why please):
All the pumps, valves, flow meter and heater seem to work OK.

I notice that the tests are timed rather than cancelled by a sensor eg the drain cycle in the test runs for 1 minute.

Would it be safe to assume that when the machine is running, the drain cycle will be ended by the sensor saying that the machine was empty rather than a timer running out?

I see no level sensor on the diagram. The only sensor seems to be the Nephelometer (turbidity sensor). Interesting things these, they don’t measure the cloudiness, but the light reflected by the bits of muck. so something stuck on the sensor might confuse it. Do these go wrong? What is the failure mode? (I havn’t washed any motorbike bits in it for ages)

So my thinking at the moment is the muck sensor or the control board (the cost of these two is about the price of a new machine, so I need to narrow it down to one or the other).

Anyone got any ideas?

Thanks for the encouragement Martin, I need it!

I am training the lumpy front to use the machine in test mode, she can manualy time the wash cycle and determin how long it takes to seperate the spot welded dinner from the plates 😯

Re: Baumatic BDF 683 SS Locking up

I’ve chosen to try and fault find raher than parts change. Looking at the cost of parts if you don’t identify the fault first time, it is not worth fixing as the cost of a new machine is about the same as a board and a sensor. I was kind of hoping that someone might know about these machines.

I have sourced a parts list and circuit diagram. I also have a copy/description of a BDS67x machine self test program which seems to work on this model too. It is similar to the procedure described earlier except the test numbers count up and I have a description of what the machine is supposed to be doing. I will let it run its course and report back, if anyone is interested…

Re: Baumatic BDF 683 SS Locking up

As there is little tech about this machine I thought I’d put up what I can see of the test mode (pressing the far right button advances the program to the next test)
Test 18 ?
Test 17 Long beep then machine fills
Test 16 Wash. Top bar only spinning
Test 15 Open soap tray
Test 14 Wash. Top bar only spinning
Test 13 ?
Test 12 ?
Test 11 Drain
no test 10 as my machine fails with error code b7. I think it fails test 10 rather than test 11.
Where I cannot see anything happening during the test I have put”?”, I guess these are things like heating element tests or what ever. Each test lasts about ten seconds.

The error code is curious, it is not the normal “E” number mentioned in the user manual, so what I realy need is the service manual with service fault codes or whatever.

What would be realy useful would be a description of each program (eg: fill, heat, spray, wait, spray, drain, fill, soap, heat, spray, drain, dry).

There are also a level sensors and one for detecting how dirty the water is in the sump. They look like optical sensors of some sort, curious to know how the feedback from these affects the function.

No info means that I am fast becomming the world expert on this model, but nowhere nearer to resolving the issue.
