Big Bosch, Little Bosch.

Me and Rob want a snazzy Bosch now too!

Hi Richard and everyone<br
I can tell you Richard, that myself and Rob were mighty impressed by your Bosch WFF! So much so that we are now dragging our ears along the ground listening out for a lead towards one of our own<br
A really smart looking machine, with superb simple and clean lines. Love the piano keys, although still havent got my head totally round the dials (could never figure out square door Bendix's either)
No worries on that point though - just makes me want one even more. Adds to the mystery<br
Ah well. The camera is going through a 'take a crap photo' phase, so the quality isnt that good, but here is a piccy from the weekend when we saw it and the compact dishwasher. You found that matching dryer yet Richard<br
Pau
p.s I did take a 5 minute video of your WFF Richard. Let me know if OK to upload to youtube<br<br

Hi, sorry for taking so long to reply, been really busy with work etc<br
Rob, Next time you come over I can do a slide show and get the cine films out lol.That's the whole fun of the little bosch, spending 30mins trying to get as much in as possible. lo<br
Paul, I think you would be really pleased if you got one. I think it's def one of the best modern machines of the time and please upload the video to youtube that would be great<br
Ric

Please forgive my ignorance,

How old is the Bosch WFF? They were sold over here, but some parts are NLA. John has one similar to that. He made it out of 2, I believe. Does this machine spin after each drain?

Does the dishwasher fill with cold or hot water? Which cycle do you use for a mixed load of dishes, 2 or 3? How long does the cycle take?

Thank you for sharing pictures of and information about these interesting appliances. I hope you enjoy them for a loooong time. Tom

These frontloaders are two series before the early "porn" XXX models (Maxxx, Axxxis, Nexxxt, Classixx, Exxcel ...).
So they are mid - late nineties. this is the last serie with mechanical timer, the following one has the same look but one dial less because of the PC board. These machine have a better built quality than current ones

As for the dishwasher in the link you can see the specifications of the last machine of this compact serie :

current serie

the model in the previous link is no more available. I ran into that link because bosch-home.co.uk forgot to upgrade the dishwasher home page.

These are current machines. They are a bit larger cause the controls now are no more on the side but under the door

see it washing with open door !

sorry i wash wrong, the washer is early-mid 90s

Give a glance to this vid, it's worth

Also the other one "what's goin'on inside"

Yes, that's our Bosch we had to use when the AEG packed in. The AEG took 150 min for the ECO cycle, which I used most of the time. The Bosch was just 50 minutes. We bought it back in the 90s, then stored it after several years of use because we bought a house (with a full-sized DW). After about six or seven years, we had to use the small Bosch again: I just hooked it up to water and electricity and it worked right away. Great little machine! And the new spray arm (without the angled jets) made it even better.

Pretty cool demo. Thanks for all the information! When it says cold water fill recommended, does that mean it cannot be filled with hot water? What about warm water? Would hot water damage the fill valve? Seems like it would shorten the cycle time.

Valves have no problems with water 140-150°F hot, whatever brand. I and my relatives who own a DW have always had hot fill cause with the gas tankless we save on electric bills.
Never have had any problem

In old machines cycle time was heavily shorthened. In my vintage miele G507 set @ 120°F the thermostat didn't stop the timer so a 2x prewash + wash + rinse + rinse + drying took just 30 mins. The same full cycle @ 140°F took 45 min (it had a 3000 W coil.

Current machines aren't so affected. My sister's miele cuts down only 15 mins on a 2 hour cycle

*Why Bosch siemens recommend cold fill*

Bosch/Siemens recommends cold fill to enhance drying.
While Miele, Bauknecht(Whirlpool) and Electrolux brands have a air heat exchanger to condensate steam, BSH machines use cold water in a flat tank that on the outer side of the tub.

This tank works also as a thermal shock safety device. It fills about five minutes before each drain to use the heat coming from the tub to preheat the water for the following fill. It does not fill before the last rinse drain.

It fills with cold water in the middle of the drying step to cool down the tub wall; moisture inside the tub condensates on the tub wall and will be pumped out

Hi Rich,
A quality bosch washer youve got yourself, there are still alot of them out there.
I know the first thing I would do is give it a good service. The most common reason for these machines being writtrn off is the motor armature buring out.
Those motors new are f*****g expenbsive.
My advice is to check those brushes I imagine there getting low by now!

I can 2nd that. I had to replace the brushes and the pump on mine recently The motor was making a helluva scratching noise on spin & then it cut out and threw up the error lights...so it was time for new brushes lol.

Condensation drying in DWs

Waste King dishwashers used to depend on the steam condensing on the tub walls during the dry cycle. Once or twice during the dry cycle the pump would turn on to pump out the condensed water. I don't think that would work with a well insulated tub. That water tank on the side of the tub wall sounds like Thomas the tank engine, the British steam locomotive that had water tanks on the sides of the boiler.

I checked the Bosch website. They do not offer the countertop dishwasher in the US. Disappointing.

The tub + "flat tank" assembly is *wrapped* with an insulation mat. Euro DW have no more the old exposed calrods since 15 years
Condensation drying is effective, provided rinse aid is used.

Machines are even quieter than a fridge. With the previous link of the countertop machine, look for Siemens dishwasher vids to have a clue : you'll hear just the noise of water splashing on the plastic foil.

Lab/surgery washers (e.g. SMEG and Miele) also use condensation drying. The incorporated condensor unit works with a separate feed/drain. I go crazy for this one in the vid, with a double glass door ... see it wash :
