grohe showers

[ambrosia]

just so I'm totally clear and there is no room for any doubt 'I hate grohe showers'

I will be starting a club/support group for others with similar opinions, membership will require a pledge to hate these stupid showers with particular venum for the avensys

 

[archiedale]

Why ?

 

[Shower Engineer]

As above, WHY? It is a great shower!

I like Grohe products!

 

[ambrosia]

customer had one where it was no longer reaching temp, water is luke warm
diagnosed fault to be thermostat, none of the local merchants could find the part, had to ring grohe to get part number, terrible customer service and their tech people are literally useless.

Took shower apart and removed thermostat, and its not easy taking those showers apart, sirclips everywhere
luckly thermostat had part number on it as this shower had no isolation valves, otherwise i'd had to leave customers water off
Put shower back together which is a nightmare balancing act
Back to merchants only to be told part needs to be ordered in and will take 3 weeks!!

Finally got the part, fitted the new thermostat and the problem is worst, also this time while taking the shower apart another plastic part broke

Told customer given the difficulty getting parts etc this shower would be easier to replace and that i didnt think they were too expensive

Just went online and recommended retail price is £398.60

Grohe are usually talked about as a quality brand.They have a 5 year guarantee.Was this one out of guarantee? Disappointing to hear about difficulties servicing them and getting parts.I noticed a Grohe parts clearance shop on ebay,parts are certainly not cheap.At their prices you certainly want to be able to repair them.Some stuff which is cheap and cheerful you expect to bin after a few years.

I used to fit them a few years ago on top end new builds but I thought at the time they would be a pain in the future for maintance. I went to a triton pressure compensation shower valve a few weeks ago total pain getting a replacement service kit cost a fortune.

Got an avensys classic giving me a head ache. Read up about the wax stat and slider, change both as the slider breaks. I didn't break the slider, typical, but changed it anyway. No the things won't switch off. A quick look says I need a new control assembly, but they're expensive, anyone got any cheaper ideas?

I have got one of these also that is giving me a head ache. No hot water. It gradually got worse so cganged changed wax capsule and ordered slider which also didn't break. Still no hot water. Cgeck to make sure the spundle is moving up and down and is. Check filters and all is clear. Doh

Got this apart and the control valve in my hands, does anyone know If it can be stripped or does it just need replacing?

How did this go feller?

It's still in bits on the dining room table! I can't get the control valve apart. Im going to try grohe technical if I can get a number for them. But judging by how many people hate them, I'm going to bet it's fubbard and needs a new valve, which is expensive. It's only just had £30 of stat and slider put in it though, so do you say forget the £30 and replace the whole unit or buy a replacement valve?

Ok, I've fixed it. Cost - pence.

Follow the step by step guide to removing the shower components as described in the manufactures instructions. Once the control valve is out it stops there. What you need to do is take the little circlip off the small spindle in the centre which controls the water temperature off. Now hit the whole unit off something hard, I used some thin carpet on a concrete floor. The valve should come apart in several sections. On the inside of the control valve assembly, there's a large o-ring. I replaced this, smeared silicone grease over all the o-rings and assembled it back together, the small circlip being a right pain. Then follow the instructions on re-assembly, paying close attention to the back screw position.

Hi,
Sorry to resurrect this post but I have been wrestling with an leaky Avensys shower for the last week and would be grateful for a bit of guidance.

I had replaced the thermostat and slider from the rear of the unit and that went well. However the repair caused a very very slow leak/drip. Yours is the only relevant posting I have found.

May I ask which O-ring you replaced to stop your leak. By "large", do you mean the largest o-ring (3mm x 38.4mm I/D)?
[There is also a vertical/facing o-ring (~2.75mm x 38.0mm I/D) and a concentric o-ring (2.4mm x 32mm I/D)].
I also found a small o-ring on the temperature control (3mm x 12.5mm I/D), another inset o-ring for the slider body (2.4mm x 34.5mm I/D) and a very thin o-ring on the shaft (1.5mm x 15mm I/D).

Happy New Year
