    Can't access Miele Tumble Dryer Motor T650C

    Hi, Our stacked washer/dryer is in a utility cupboard, conveniently part-blocked by a wall-mounted boiler. Removing the dryer won't be easy, so I'm trying to strip/repair in situ (i.e. front access only). It's been making loud rumbling/grinding noises and drum has been incredibly hard to turn...

    Quartz and Digistat problems WB 35CDi Mk1

    Things got worse when the Digistat receiver failed to pair with the transmitter, and as each component costs about £100 each, I got WB in. I figured the system had worked for years without fault so I didn't think the failure was due to RF interference... turns out both the transmitter AND the...

    Quartz and Digistat problems WB 35CDi Mk1

    Hiya, and thanks again for this valuable info. Yes, I have heard (and seen) mobile phones do *all* sorts of things to nearby devices, so I can see how my Digistat could be affected by all kinds of nasties in the modern home. Really, though, I can't leave my DECT / mobile phones off and have...

    Quartz and Digistat problems WB 35CDi Mk1

    Just reading up on Wifi networks... they operate (usually) in the 2.4GHz range. I don't know much about radio interference but would have thought that wouldn't have too much affect on a Digistat operating at 418MHz, right ? DECT phones, microwave ovens etc. yes... but wireless routers ????

    Quartz and Digistat problems WB 35CDi Mk1

    Darn. Either the stat or receiver have malfunctioned as they will no longer pair up. Possibly my helpful circuit prodding didn't help... I suppose the interference could be sooo overwhelming they can't hear each other, but I doubt this as I've tried to pair them a dozen times or so. I...

    fab. Will attempt kludge tomorrow. Thanks for de-rusting the old grey cells !

    Quartz and Digistat problems WB 35CDi Mk1

    Hi radio_eng, Not sure that works though as: 418/300000 = 0.00139 (metres you say) X 100 to get into cm = 0.139cm which is a seriously short length of wire, LOL, especially if I divide it down further ! What am I doing wrong ? :?

    Quartz and Digistat problems WB 35CDi Mk1

    Thanks breezer - this fault was beginning to drive me nuts. I notice that the newer (I think post 2000 / 2001) Drayton Digistats operate on 433MHz instead of 418. Possibly they suffer less from RF interference ? Before I go out and buy a wired programmer, I am thinking of fudging a long...

    Quartz and Digistat problems WB 35CDi Mk1

    Hi Nick, Thanks for the reply. Funnily enough.... I came back from holiday and I noticed two new wireless routers show up on my Mac... good for free Internet access in emergencies etc... but are you saying BAD for digistats ? I thought they were playing in different radio frequency...

    Quartz and Digistat problems WB 35CDi Mk1

    I've got two problems with my boiiler: 1) Shower goes from hot to cold and back again rather than staying stable (argggggggggh). This happens intermittently. (Everything was previously OK for years; the Quartz processor is the correct one). 2) Wireless digistat thermostat and receiver...

    Query on Expansion Vessel re-pressurising, replacing PRV

    Thanks all, especially croydoncorgi for my lesson in the black art of EV pressurisation. I am now toasty.javascript:emoticon(':lol:') For any people following this thread trying to learn how to check / pressurise their EV, I did indeed need to dump *a lot* of water out the system to drop the...

    Query on Expansion Vessel re-pressurising, replacing PRV

    Cheers to all. Brain expanding pleasantly. How come, then, if EV pressure needs to be optimally set at approx 0.5 + static head (in my case say 5m or 0.5 bar), and low EV pressure can result in excessive system pressure when all rads on, pumps circulating, does the industry not fit air...

    Query on Expansion Vessel re-pressurising, replacing PRV

    Hi, Doitall, The EV is sound: schraider valve does not drip water. Only air comes out when we offer up the pressure gauge. I am just trying to understand if at my 1 bar minimum system operating pressure (as per WB manual), my EV should just be pressurised to 0.5 bar (factory setting), or...

    Query on Expansion Vessel re-pressurising, replacing PRV

    OK. PTFE vanished. Found some nice pipe jointing compound instead. Kevplumb / others, I feel like a wallaby, but can you confirm precisely how I figure out what the EV air pressure should be, and when in the refilling process I should be achieving this. I ask because the boiler manual states...

    Query on Expansion Vessel re-pressurising, replacing PRV

    Thanks kevplumb and ChrisR. The flushing out of the PRV was only a temporary fix: it began leaking again after a few days. I have now acquired a spanking new (correct WB) PRV from www.mjtcontrols.co.uk. and am about to fit it and repressurise the EV. Q: Should I use PTFE on the PRV...

    Query on Expansion Vessel re-pressurising, replacing PRV

    Boiler / Problem: Worcester Bosch 35CDi MK1 combi (4 1/2 years old) / pressure drop to zero, re-fills repeatedly drop to zero over a day or so. I've spent several days reading through messages about pressure drops through leaky PRVs, checking EV pressures / filling loop valve leaks etc. and...
