Hi Gary,
I bought a new safety plug from you, as the old one was leaking, after fitting this one has also gone ! I did notice after that the thermostat was set to maximum. Is the burner/thermostat faulty ? It does usually give a loud pop when ignigting - but I thought this was normal.
Just want to know if I should order a replacement burner unit along with another safety plug, or turn the thermostat down & try just fitting another safety plug.
Cheers, Steve.

The maximum is 65degs and the fuse blows around boiling point so it's doubtful turning it down will work, I think it will be a fault on the control board and it won't shut down at any set temp.
The other thing is it should not light with a "loud pop" and for this reason alone it should be changed.
One other thought is the last one leaking and it depends how bad the leak was, but this may have allowed water into the electronics and caused this fault?If you do have both as a slight saving to you call it £65 total

maggie - that is a tough one -
If you are using windows XP then it will open then automatically otherwise you need a program to open them - something like WINZIP or similar - try using google and search for WINZIPhope this helps

Jamie, I have drain bungs, either pre1987 which has a cross for the screwdriver or the later ones with a single slot and 4 prongs.
Both are £6.50 including postage.
The drain is sealed with a rubber 'O' ring and when this wears the bung will leak, probably over tightening yours is why the bung broke trying to stop a worn 'O' ring leaking??
Regards
Gary

HiThe Carver Cascade 2 water heater in my 1997 Swift Challenger has developed the old problem of firing up and then cutting out. Are there any details/notes available on how to service the gas burner. I have good gas flow pressure and battery voltage so this only leaves the burner to be at fault.

The real problem is the flame recognition circuit of whatever age is for want of a better word 'delicate' so easily disturbed for half a dozen or more reasons. Where age does come into it though is more to do with who actually supplied the control pcb than the fact it is several years old!!. 97/98 module for this reason suffer from the same faults, provided that is, leaking water has not played a part which will damage this circuit in modules of any age.
While a competent person could in general service the gas side of a burner module the fault you have requires something more as it is electronics as well that need attention and it is for this reason I supply a 'fully Serviced' exchange unit.
These are as I am sure you have read £63.

I have just got my first caravan and seem to be having a bit of trouble with the water heater, I`ve looked around the internet and am still a bit unsure, I have a cascade 2 fitted. The problem is I fire up the heater with no problems, though it does make a buzzing sound and not being knowledgable about caravaning don`t know if this is normal, after about 20 mins the buzzing stops as if it has cut out ie the water has heated, then after about 15 seconds the red light comes on, when i run the hot water it`s fine but the heater does not turn back on. it`s running off the mains and there is no battery fitted to the caravan, the van was sitting for about 5 months prior to me buying it. Oh and one last point, what is the red switch type thing on the burner, situated at about nine o`clock if looking at it from inside the van

"Oh and one last point, what is the red switch type thing on the burner, situated at about nine o`clock if looking at it from inside the van" Starting with this question Jase, do you mean you can see it from inside the van? because if you can it dates the water heater to early 1985 and helps answer the rest of your questions.
The red 'switch' or knob is to adjust the water temperature and Carver very quickly blanked off this inside adjustment and provided a flap behind the main outside cover to get at it by the end of this year.
Assuming I am right about the red knob this would also make your van the same year so the charger provided in those days could well be the source of the buzzing as it will not be designed to work without a battery.
A battery will be needed to smooth the charger 'voltage' output and this should prevent the gas solenoid valve buzzing, for the same reason the charger 'amperage' output will be very small and will not be able to cope without a battery to help.
Apart from the 'burner module' of this age not being the best one and again if an original one from 85...prone to leak gas!!, then the rest of the faults could well be do to the lack of a battery and will settle down when a battery is installed.

Thanks Gary, I`ve looked at the heater and it is dated 1985 so you are spot on, as for the other stuff I guess I will have to invest in a new battery and see what happens, it`s good to know there is good profesional advice out there, thanks again

Hi Gary,
Whilst trying to remove the thread of the pressure relief valve(which had snapped off and was left in the Cascade 2 housing no. W62902), I have damaged the housing.
Can you please advise if a replacement is available?
thanks,
Roy

Who's been using a stud extractor then Roy??
Anyway I do have repaired heat exchangers as well as one new, these are £45 or £98 +P&P. The repaired ones are 'bare' but the new one is complete with all the plastic fittings, both types are exchange.

The lack of a green light as this is powered direct could simply be the LED has blown?, The red is lit by a signal back from the main control in the burner module and should come on after 8 or 10 seconds of switching on if there is a fault. The yellow light is to show low battery voltage and because of this you should always see it flash as you switch on and off.
The fly in the ointment is this Harmony battery charger, I would switch this off and run the heater on a good battery alone, this will tell if this thing has anything to do with the problem before we go further.
PS when you say "press" the on button, do you mean press down for on and push up for off?, or have you two push buttons?

hi gary,
thanks for your prompt replay, Ihave turned the charger off and just run on battery but still no results. I have 2 push button 'on' and 'off'. When I press 'on' I can hear the relay clicking inside the small panel but I can't hear any other sound from the main unit itself (I don't know if I am supposed to hear another click of the gas valve etc etc). Yes It could just be that the green led is dead since I have measured about .8 volt across it, but what it looks like it that when pressing ON the relay should latch in that position instead it doesn't... (hope I have explained myself !!) Again a big thanks for your time regards riccardo

Thanks Gary,I'm never going to touch another stud extractor again. I don't know my own strength. I'll contact you at Arc for the bits.
thanks,
Roy

I assume you mean the green is always lit Davy?, well it shouldn't be so theres a problem somewhere. Try disconnecting the lead to the module and see if the green light goes out then, if it still stays on it's a problem with the control switch. There are to types of control switch and 1995 is around the time they changed, the earlier one has an up/down action to turn it on and off, the later one two grey push buttons. Sometimes the on/off switch itself is part of a bigger control panel and this way it will be a 'rocker' type switch but this only controls an earlier type control switch that will be hidden under a bunk...which do you have??
