- My aqua hot electric heat did not work. After downloading the manuals, I opened up the unit and found that the AC high limit relay was bad. This video shows the opening of the aqua hot, electrical panel and replacement of the relay. Then the subsequent reinstall of the aqua hot.
Affiliate link to the multi meter used is below. It has AC/DC voltage and AC/DC amperage readings and is only $47!

...and yet another reason that a simpler coach is better -- You didn't need to disassemble too many other things to get to what you needed to work on! The typical Aqua Hot service is something like $250, and a part like that is additional. You saved a little money by doing it yourself!
Agree. Some coaches you can’t even see the aqua hot. Thanks for watching.
@@CampPrevost i cant see mine!!!!!!!!!
😭😭😭😭😭😭😭😭
Great job !!
Thanks!
great video!
Great job!
Thank you - was hoping this video would help someone if theirs quit working. Thanks for watching.
Hate to be 'that' guy but as a retired appliance guy I have to be lol.. you replaced a thermostat, and saved yourself several hundred I'm sure good job!
Ha - your right. Was looking at some switches this evening and found some WiFi controlled relays. Put kids to bed and put this video out - so I called them relays! Lol. Thanks for watching. One thing concerning me - I did the ohm test and the electric element was within the values listed, and you have to drain the hydronic fluid to change it out - so I left it. When I powered it on, it was pulling 14.2 amps - the book said 11.2-13 amps. Do you think that’s ok? Was thinking maybe it’s pulling to many amps and that’s what burnt up the relay (thermostat lol)?
@@CampPrevost Saw a couple thermostats in there that will cycle the element depending on the heat settings another will be a thermal cut off incase of an overheat, any of those open will cause a no heat. If the sheet says 13 amps I'd assume it's a no more than a 1200-1300 watt element but a higher watt element will draw more amperage so if it's the correct wattage drawing slightly more amps may be age, possibly on it's way out but once the element goes out you'll have zero ohms across it's leads as well. Might be a good idea to have one ready. Hope that helps some. My experience is with residential but but seems similar enough as far as the heating operation.
Just wondering if you could tell me the basics on AQUAHOT. Mine works fine, and I learned how my thermostats work inside coach. They share the same thermostats as the toe kickers and to diff the 2 I have to flip a switch that says "aquahot/120V". Its extremely difficult cuz I cant find my aquahot...but i imagine is somewhere near the exhaust it spits from. My question is...am I suppose to just eave it be? Do dials to set for its on? how do I know if it needs coolant? etc etc......
Quick simple summary. Its just a boiler - it has a tank of coolant and a tank of water in it that gets hot. It gets hot by an electric element - that has a few sensors on the tank itself - it is run by 120v. It is either on or off. It is also heated from a diesel heater - that pumps high pressure diesel and ignites the spray to heat the tank. You can run both, none or one or the other. It is also heated by your engine - as your engine coolant gets warm, it runs into the same tank. So you can take a hot shower or heat your coach while running down the road. Your thermostat should have a setting for heat - not heat pump - that will turn on your toe kick heaters. You also have electric toe kick heaters. Hope this helps!
@@CampPrevost interesting on thermostat. So mine has like a master switch that tell the thermostats which heat to control/turn on....if I select aquahot...it controls that, If i select 120V...then it controls electric heat. my electric heat is shot right not, aqua hot heat is amazing..
