Coleman hot water on demand issues
« on: January 01, 2013, 10:20:58 PM »
I have just recently used my unit for the first time, charged the battery for 24 hours before using. I managed to get 20L of warm water through, I refilled the contained and went to use it again with no luck. There is nothing the pump and the igniter don't work it's like there is no power. The battery has been charged again and still nothing. Has anyone experienced this before and is there a fix.

Cheers
Russ

If it is out of warranty there is a fuse inside them that is covered with a light rubber coating, it is the common glass style fuse. That may be causing your issue assuming the battery is ok. The batteries die regularly too especially if it hasnt been charged and is sitting around.

And silly as it seems make sure the pump unit is plugged in properly, were the water enters the unit. I did in a past life knock that out a bit.

I just re-read your post, it sounds like it is brand new, if so dont open it looking for the fuse ;)

You wouldnt have your charger still plugged in by any chance?

I bought the unit new in may-June and have never used it, I also brought it from an on line eBay camping store so my chances of warranty are practically nil
I didn't have the charger in, but was wondering if there was a way to modify the unit so I don't have to use the supplied battery.

Did you check the plug I mentioned......

The pumps runs off 6 volts so you can do a mod but you will need to pull it apart to do that. I built a small 15 buck 12 to 6 volt converter and changed the charge plug so it did no shut off when the power supply was plugged in

I have checked the plug that seems fine I have opened up the unit and am having some difficulty locating the fuse location, any clues?
Is it accessible once the cover has been removed or do I need to remove other components to get at it.

Ok u blew the fuse for a reason. Most common cause is the pump has jammed due to water scale build up on the spindle of the pump. When u try it- watch the green led on the front. If it dims and pump doesn't work quickly turn off. Remove screw cover on bottom of pump and u will see small impeller. Turn this with a small screw driver just to free it up. This should sort it out if it is the problem. Hope this helps. Trick to packing these units away- drain all water from pump and hose by first running for a very short period ( about 5 seconds ) without any water and the. Allow to sit upright to finish draining and dry off

Saw this on a thread once about running the Coleman off a 12 volt battery, not sure where I saw it, but I copied the text.  This is part of it.

Used a 5amp 12 volt to 6 volt car power adaptor from jaycar (part no. MP-3478) wired it with 3 meters of 12 (AWG) wire (this is important) & soldered spade connectors to wire ends to fit on to battery terminals.

Most annoying when the small Coleman battery runs out  of power!  Some people carry a spare as they are pretty cheap.  But being able just to run it from your camper battery would be handy.

A member has kindly posted pics and diagrams about how to do this using anderson plugs etc etc on another forum, click on the Coleman Hot Water On Demand Review and look through the posts, there in there at the bottom of the first page and the second ..Of course do it at your own risk and especially don't do it while its still in warranty unless you want to void it. ..

Heres the link for it: http://www.4x4earth.com.au/forum/camping-equipment/26322-swaggies-product-reviews.html

Goodluck
