Bewdy….those nice people from Bosch are going to replace the oven with a new one.

Cheers….Valvo

Bugga….seems I’m unlucky with this fault, it’s reared it’s ugly head again.
Beginning to think this oven is a lemon .
Once again the oven has just reset itself whilst cooking.
Mrs V had Greek roast potatoes cooking at 160C Hot Air Grilling with just the timer counting up, went by the oven 5 mins later and the
program had reset….the central round dial just showed the current time and a ring of red around it to show it’s still hot yet we have used the oven
since and it works perfectly.
Back in Nov2018 the perfect bake failed to produce a cake using the same recipe that has been used before, interestingly the next day we noticed the oven displayed an incorrect time .
Dec2018 the thermostatic probe in a chicken indicated it was cooked but juices streamed red blood(core temp 84C)….I’ve told Bosch this is a health risk.
Xmas turkey was outsourced to my son as we just cannot rely on this oven anymore.
The retailer is sending out on of their engineers to do an assessment as I have asked for a replacement under Australian Consumer Laws….I consider it not fit for purpose.
I have tried 5 times to replicate the fault but cannot.
The Bosch engineer checked out the 240V power OK, it has it’s own 32Amp fuse, any power glitches and TV and computers reset.
Today I checked the door switch but if that is dodgy it brings up an audible alarm and tells you to close the door.
All the cooling fans are working OK.
Not sure if it is a fault but the Childlock only locks the oven controls, not the oven door, yet door locks for Pyro clean.
Am I unlucky??? or is this a familiar fault?

Re: Bosch Series 8 Intermittent Timer Problems

Well I got lucky with this fault…. called up the extended warranty people and they said it was to complex for a generic repairer to deal with so they sent out a Bosch engineer.
He took one look at my documented faults and replaced the whole front control panel flashed it with the latest firmware and everything Mrs V cooks in it comes out perfectly.
No faults for over 6 mths now.
We also noticed this oven draws a lot of cooling air from under the front bottom lip so modified the kitchen cabinet so it is no longer partially blocking the intake vents. Whilst he did not think it was the cause of the faults I’m hopefull it will extend the overall life of the oven.

Re: Bosch Series 8 Intermittent Timer Problems

If the oven loses power whilst being used you would have to input the time and date again (consistent with a loose connection, dry joint or supply failure)….this has not happened.
The program just goes back to its dormant state without an end chime.
I have searched Google and cannot find any info on a self test program so today I’ll investigate factory reset and do a power cycle then monitor and record any faults.
Turns out I purchased a 5 year extended warranty and we are only 14 months into it.
I have recorded the details with Bosch customer care and the extended warranty people but both will charge a callout fee if no fault found.

Re: Bosch Series 8 Intermittent Timer Problems

Hi Dave,
I wouldn’t have thought a timer is really putting the oven under load but I will check.
It is supplied via a 32A cct breaker (240V in Oz) and I recall supplied cord plugs into back of the oven.
The oven works perfectly for all types of cooking since we bought it 14 months ago,
other than about 7 months ago Hot Air Grilling turned off and the Timer failed twice in the last week. I tested it twice today and it was OK.
If there is a self test program I really would like to run it. 😉 😉 😉

Re: Bosch WTA3200 not drying on auto cycle

Fairly certain the problem is on the pcb, noticed some smoky burn marks inside the relay canisters. Also it appears the front and back drum bearings (felt?) are worn so it has gone to re-cycle heaven. Put it out the front of our house with a freebie sign on it and it was gone in 45mins.

Thanks for the help blokes….Valvo

Re: Bosch WTA3200 not drying on auto cycle

Thanks qas…I’ll check it out on the weekend, I remember checking the element and cut-out thermostat were OK but not the other one.
No urgency anymore, after 30 years of Bosch in the laundry I have reluctantly joined the Miele ecosystem with basic TDA150C & WTA110 delivered.
Main complaint with Bosch/Siemens is the sealed drum and difficult (expensive in OZ) shock absorber replacement.

Re: Bosch WTA3200 not drying on auto cycle

OK I tried again and got a reading of 17k at 11degC and it dropped down to about 3k after a bit of heat.
Do those readings appear within spec?
Won’t get a chance to remove PCB until the weekend as it’s cold and dark outside by the time I arrive home at night.

cheers….Valvo

http://www.bosch-do-it.com.au/au/en/diy … 0-dce.html

don’t worry will set it to 75degC

Re: Bosch WTA3200 not drying on auto cycle

Thanks Martin, I’ll check the reading again and hit it with a heat gun and see if it varies.
I’m wondering if this model is a rebadged Bosch from another manufacturer(Crosley?) as it was also sold in Oz as a Kleenmaid.
From memory it heats for 2-3 mins in anti-clockwise direction, then reverses for about 20 secs….I only feel heat for the 20sec clockwise direction.

Re: Bosch WTA3200 not drying on auto cycle

Time to resurrect this thread from 10 yrs ago.
The machine has worked fairly well up until now, SWHMBO used it on the timer for 6 years and then it mysteriously fixed it’s auto cycle problem.
But now it only blows hot on the clockwise cycle(very short cycle) only with the timer.
The element and 2 rear thermostats check OK so I will remove PCB and check for dry joints etc and maybe change the capacitor.
How do I test the probe mounted in the front panel airway?
Is it an NTC device?
There are a couple of brown wires from the PCB that appear to go down to this probe and it tested open cct.

cheers…Valvo
(Oh, also the fault co-incided with Aust losing the Ashes) 👿

Re: Bosch WFL2400 "tankslaps"

Well I managed to pickup a kit containing a pair of shockers from a German Ebay site for 75Euro delivered to OZ and nearly 1yr on I finally fitted them yesterday.
These Thai built machines we get here now only have a removable front panel so I found it easier to remove the whole drum to drill out the pins. It all went back together OK, I loaded it up with towels and it was better than new according to Mrs Valvo.
I very much suspect it’s the towels we tend to use in OZ that are causing an overloading problem, they are 1600mm x 800mm and are very heavy when wet causing unbalance where-as in UK and europe the towels are much smaller. I guess it makes them much easier to dry and gentler on the shockers.
I now know of 3 bosch machines that have had failed shockers but interestingly both my kids have 8 yr old locally made Electrolux front loaders that get overloaded and are bullet proof.

cheers…Valvo

Re: Bosch WFL2400

Bugga….time to do the maths.
$200 for new shocks + coupla hours for me to fit.
Or an extra $500 for a new WAE24272 AU with 2 years warranty and keep the old one for spare parts, or $472 for an el-cheapo 7.5kg Samsung which is getting good reviews in OZ.

cheers….Valvo

Re: Bosch WFL2400

Thanks Martin,
but is it a kit of two shockers?
My local Bosch repair shop couldn’t tell me….they say because it is 8-9 years old just dump it and buy the new one for $699.
I have since found out the part # for the friction shock is 642112.
http://www.amazon.com/Bosch-642112-Damp … hine+parts
They appear to be sold individually.
The kit 448032 also appears to be sold individually also
http://www.appliancepartspros.com/bosch … 54511.html
These are both USA sites though.
Looks like you drill the pin out, would you take the front panel off for access?
cheers….Valvo

Re: Bosch WFL2400

Cheers from Sunny Sth Australia…..well 3 years later and I have finally got around to pull the machine out and looking at this problem again as it has got worse.
The model number is WFL2400AU/20FD made in Thailand.
I have disconnected the bolt at the base and the shock absorber shaft is wobbly and has no resistance moving in and out.
The local Bosch guys are a lot more helpful now and have told me the part # for the shock absorber is 448032 $95 for the kit. I don’t know if that part # is for the friction type.
Now when I punch that number into your spares website it shows a tubular shocker 433761 45Pounds
Has any-one retro fitted the friction shocker with a tubular one?
Does the kit have two shockers?
Here is a link to some pics https://picasaweb.google.com/Valvji/Bos … directlink
