Alde 3010 electric heating not working

[DavidG58]

We had ‘weak’ heating when away earlier this month and put it down to being cold

We now have no electric heating luckily at home but MH being used over Christmas, everything works properly on gas so not a crisis, but needs sorting

The hook up symbol is on the Alde control panel, there are no fuses tripped, so I am thinking failed electric elements in the boiler itself

Testing that is way beyond my skill level, but I just wondered if there might be a trip of any kind on the boiler itself, ours is boxed in and quite hard to access, including needing to empty a lot of ‘stuff’ to get near, no point if nothing there, anybody had a similar issue ?

I have RTFM and found nothing in there

Suspect we will need a service visit to Alde in the new year, or just abandon the electric side which has never been very efficient

I would have thought that if an element had gone it would have tripped the switch also it would be unlikely that both the 1kw and 2kw elements had failed.

Alde 3010 not working on electric

Hi, pump runs but not heating up on electric, 2 or 3 kw. The little plug symbol on the 3010 control panel is not showing even though we are on ehu and all else 230v working. before I call Alde on monday anyone have any ideas? Is it the control panel or boiler. Van is a Dethleffs Globtrotter. Thanks

Do you have a Voltstick ?

Hi David,
That's a tough one to try and work out.

Have you tried selecting different electric power settings to try and see if it is a problem with the 1Kw or 2Kw elements or whether it's a common problem. There are some fuses on the main PCB but we know what a pain it is getting to them.

I don’t but do have a smart meter display which confirms no power being drawn whichever setting I use between 1,2&3Kw

With the plug symbol being on the display, it seems logical that the Alde unit can see 240V

The unit is now 20 years old and for the last 12 years has been on permanent hook up when at home with the Alde unit set to 9C so it had done some work

ON our Alde 3010 someone once suggested lifting the grey plastic cover to the terminals, removing the red connection, count to 15 and plug it back. Voila ! it worked. Heavens knows why .

Logic and motorhome issues never go together lol.
It seems odd that both elements have failed so I would say it’s more a control or fuse issue.
Your smart meter shows no current draw but is that because there’s no power being used - element broken or is the switch not telling boiler to use electric, or is switch saying start up but temp sensor not triggering.
Is the alde heater on separate trip circuit or combined with anything, is anything else working on circuit.

We are away again and now definitely have no heating on electric , although the hot water works on mains which must have its own element

We have pulled the wire out and thankfully got it back in, I did imagine we could go to no heating at all

But all now reset and sadly no change, but gas is doing its job very well

Now need to decide whether to pay for new electric elements or Alde intervention or just use the same funds to buy extra gas

Happy New Year everyone

You could just buy a small electric heater for not to much and plug it in when on electric, we have a small ceramic fan heater that we carry for back up and find it actually heats the van far quicker than ALDE on electric.

Happy new year

Must be something else going on if you're getting hot water when using EHU and not gas as the heating elements are in the glycol which transfers the heat the water. (which is why you can run the heating with the water drained down.

Don’t remember there being a separate element for hot water so thinking there’s a relay not bringing in the 2kw part so you just getting the lowest power. Have you the option to set a reduced amp limit for 240v use, that would give the results you are getting.
As gas working it proves the sensors for room and boiler plus pump work so only leaves the power source.

Possibly just enough heat for the stationary water to heat but radiator glycol cooling as it travels?

Also if there is a load monitor fitted it will reduce the power available to the elements to stop the trip tripping.

No load monitor we probably predate those specs , I doubt the water could get as hot as it does by associated heat, it’s often too hot to use

Hi David, as Richard RB62 says the hot water jacket sits around the glycol so picks up heat indirectly, if the domestic water gets hot the glycol heating fluid must be hot, best of luck and best wishes to you and Bev for 2025.

Been in touch with Alde, they think it’s a board fault with a relay not functioning , they say an element failure would normally cause the RCD to trip

Estimate under £500, but it’s a £280 board, they can’t see us before 7th April but I have booked that slot

I had recalled correctly they have 2 elements , 1 x 1Kw and 1 x 2Kw

Bit more learnt about our Alde, might be useful to others maybe

I wanted to find out if the water heater had a separate electric element to the central heating

Turned gas off in controller and put electric on 3Kw, ran hot tap till water ran cold, checked again 2 hours later, still cold so there can’t be a separate water element

However, as other 3010 owners will know you can’t turn water heating off, even if heating not called for you still get hot water. However when I finished my checks yesterday I left electric and gas both turned on, even though I know the electric room heating has failed

It would appear that unlike the room heating which I understand will use both gas and electric if electric isn’t warming up quickly, the water doesn’t recognise that the electric element has failed , only seeing the mains is connected . Then compounded by me turning on a new 600W fan heater to try overnight, which brought the room temp up to 16C but meant the Alde heating didn’t cut in, we had ice cold hot water today

For those that don’t have Alde that will be very confusing, quite probably even if you have it it might just help someone

Not sure now what set of circumstance I might be able to use that new found knowledge , but if hot water not wanted and not hooked up turn electric and gas options on but turn thermostat down

Only circumstance you might need those characteristics, you would simply turn the alde off lol

I am inclined to agree with you, but there have been times when hot water hasn’t been needed to run all day, but heating was nice to have

Save a few drops of lpg when off grid maybe

More trouble than worth though I now think

But when the heating is working the hot water works by default, unless you empty it.
Yours didn’t work by nature of the wall stat not calling for heat due the the fan heater
