Vaillant Ecotec 831 rubber hose

[rockinter]

Hi,
I recently saw that some of the vaillant ecotec 831 had problems with their rubber hoses and these were being replaced by vaillant to copper ones. I rang up vaillant and they said as it is out of warranty it will be chargeable.
I have taken a picture of the rubber hoses could anyone tell me do i need to replace them?
Also my rubber hose was missing the filter which connects at the end of one of them as shown in the vaillant parts book. Do I need that filter and what purpose does it serve?

Thank you

As I understand there are two changes, the first being a different rubber hose with a red stripe.

The second the copper.

It seems a little odd to me that you pre-empt a problem and start taking your boiler apart.

Doing that seems more likely to me to create a problem!

The only filter I know of is behind the pressure sensor at the bottom left.

Copper ones are about £75 but why remove them if they are not leaking??? The filter is a conoe filter as tony said behind the pressure sensor

 

[rockinter]

Yeah that is correct it is the conoe filter, do I need that? As my boiler did not have it when I took the hose off?

You do not see it when you take off the pioe.

As I said its inside the black plastic housing at bottom left.

I thought you should be able to take it out with your finger, to check if it is dirty? I tried but there was nothing in there.

I am still struggling to understand why you have taken the boiler apart ,do you have a problem with the boiler!!!

 

[rockinter]

We had bit of dirt in the heat exchanger, so we took it off to clean it. And before anyone starts saying, yes we have had it powerflushed and we do have a filter fitted. I was thinking if the filter would have kept the dirt out of the heat exchanger.

we deal with these boilers everyday,i would change these legs because if they split it can take out fan and pcb due to water damage.You have done the hard part by taking legs off,£75 is cheaper than a pcb and fan

Thanks for that info, Does that come with the conoe filter?

Don't worry about the filter it's to big to catch much we remove em sometimes to help with f75 it will be there an they r bastards to get out,it is in the pipe behind the pink pressure sensor
