I've tried searching for a solution to my question, so please point me to a relevant post if you know it. However, it seems the micro switch on the bathroom tap has failed. I'm fairly technically minded but cannot fathom out how the tap comes completely apart. Does anyone have any instructions/done it before/could explain the removal process/can it be replaced in situ etc etc. Many thanks

If it's the same as those fitted in Hymers ie Reich twist tap. There's a small grub screw on the back of the lever.

The lever then pulls off to reveal anothe screw in the centre of the grey microswith holder, remove screw and pull the grey holder....

The fault with mine was a broken wire, which apparently is a common fault with these taps.

The microswitch can be obtained via Ebay or https://www.leisureshopdirect.com/w...-spare-parts/microswitch-for-reich-twist-taps

thanks you for your prompt replies.. So the story so far. Finally figured out how it all comes apart and now have offending micro switch removed (switch not faulty as such, but corroded wire had parted company from the switch and its not possible to re-solder it back on). Now on the internet to source a new micro switch with tails. I've been taking photo's along the way so will be able to publish procedure (if someone points me to the right place to do so). Anyone know where to get micro switches - only reference stamped on it is E51. Pic's attached

hi doug, i have a t660 and i changed my sink last year so i reckon you will have to remove the sink get at the bottom of the tap where the micro switch is ,there are 4 screws underneath to take out and disconnect the pipes, also there is no slack on the wires, i had to cut them and add 2 extra wires to connect them up

So, an update for anyone in the same situation with Burstner 690G.

Ordered the part No.228166, from leisureshop direct - https://www.leisureshopdirect.com/w...or-reich-taps/microswitch-for-reich-kama-taps

Tap body removal and see attached photo's
Ensure you have drained the water and ensure electric pump is off.
Prise off silver circular centre cover from tap lever using plastic spatula or equivalent (finger nail)

Unscrew centre screw with 4mm hex bit.

Remove tap lever.

Move tap anticlockwise to reveal small T7 torx screw at base of tap and remove screw - taking care not to lose the small piece of plastic that will become free inside the tap body when screw is loosened - you will need this during re-assembly.

Slide complete tap body upwards, which will reveal internal workings and seals within tap body and tap lever cover/head with wiring and microswitch inside. Carefully lift off microswitch housing.

Prise out microswitch gently. the brown wire on mine had corroded from the switch. If yours is similar, cut the two cables further down the tap body and remove the microswitch completely.
Replace the microswitch and feed new wire through small hole in the plastic body and join new wire to old wiring using small chocolate block connectors (or solder- whichever preferred). Reposition wire neatly within tap body.

Ensure Microswitch holder is exactly in position, then slide chrome tap body back over tap.
Personally, I checked at this stage that the microswitch was functioning correctly (without water) before re-assembling
Re-assemble making sure small piece of plastic is located in appropriate groove and aligned with the hole on the tap body (patience required).

The piece must fit in this grove to allow the tap to move on its axis and to stop the body lifting free and leaking as the body provides the water seal inside the unit

Refit lever with hex screw and reposition silver chrome screw cover

Turn on water and test fully......
