SOURCE: Vaillant turbomax 28 constant hot water problem.

got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps

SOURCE: alpha 240e boiler wont fire up for hot water, will for heating

most likely the diverter valve.. when hot tap turned on the movement of the water through the valve operates a diaphragm which pushes a pin/button//switch to tell the boiler to fire up

Intermittent hot water.Changed diverter valve,heat exchanger,fan, PCB. Vaillant turbomax 282e But still no hot water.


Sounds like you need a new Thermo coupler.
Could be as simple as a dirty pilot and needs cleaning but I suspect a thermo coupler.

Vaillant 209703 ABS....hot water without heating on


If you have hot water the heater must be heating. Perhaps the switch is bad or the gas on/off solenoid is malfunctioning. But, how do you know that there is hot water, is the water facet on? If so try turning off the water.

Vaillant boiler leaking only when heating switched off.


It would seem a joint has come a bit loose from the heating and cooling cycle. put a drip pan under the leaking area( the drips would evaporate quickly), then next time you shut it down go through all the joints in the area with wrenches to find the loose joint.

Hi my vaillant combi gives hot water for only 15 seconds then runs cold turn the tap off, run the water again & gets hot then runs cold some told me it might be the diverter valve can any body help...


yes it is your expansion vessel it sounds under charged to me?your expansion vessel needs to be recharged to 1 bar at least,but check manufacturers instructions it could state different.if the heating is fine and your getting hot water in intervals your diverta valve is moving and working?
