Junkers gas water heater automatic ignition not working

My water heater stopped working however when I removed it from the wall and gave it a good shake and re-fixed it - it worked fine for about a week and then stopped. The ignition is not firing up and the gas is not coming through (can't be lit by hand) when the hot tap is turned on. It seems to me some sort of valve is sticking which also shuts off the gas.............any ideas

    Our Junkers combination bioler has stopped firing up . it has in the past been able to reset by pressing the red lighted button..but now it won't light.

    Is there a reliable gas fitter in the ALCAIDESSA AREA

    There is no hot water supply from my system Dux Deliverance DX. The gas does not seem to be igniting when the hot water tap is turned on. This used to only happen when is way raining heavy, now it will not work at all.

Yes that is going to be the contoll valve on that heater. You can probley fix it very easy with the right part. You will need to locate a plumbing supply over there in the UK. Give them the make and model number and tell them you need a unitroll gas valve for it.

Is the junkers WR 11 Gas water heater ok for outside mounting

No all water heaters need to be mounted inside. Helps with the equipment efficiency, corrosion due to exposure to the elements, possibility of incoming water freezing. It\'s bad on electrical connections, the UV lite is hard on any plastic parts. These things are meant to be installed indoors.

Junkers wr11 has no spark and no power

Is it gas or electric? if it is gas and has a pilot, and the pilot is out. If you don't smell gas go through the start pilot proceedure. when the pilot is running it produces a small electric current sufficient to hold the main gas valve open; then the temperture sensor allows the unit to keep the water heated.

Flame burning too orange

You must get more air to water heater, and check venting .... immediate CO poison danger.
Call qualified plumber immediately.... because deadly carbon monoxide is not being vented properly.

Junkers gas geysers not heating water much

between 60 and 75 degrees c as any hotter will scald you. Have the gas specialist check it out as it may not be getting enough gas flow to the burner either a badly adjusted regulator or a blockage in the gas tap or line.. You control the temp by the amount of water coming out of the tap as you found out when you attempted to restrict the water flow.

I have an Atwood G6A-8E water heater. It stopped working last year so I took it to Camping Wprld. Their R&I'd the tube and igniter. He cleaned to tube and adjusted the igniter. The water heater...

Have you verified that you have 12 Volts DC to gas valve when it is trying to ignite? If you have the little thermal cut-off ( looks like a small diode ) inside plastic sleeve going to terminal on thermostat, remove it and connect female end on that brown wire directly to thermostat terminal and see if it lights.If it does, get a new thermal cut-off. It's a safety device so don"t go without it. It shuts off gas to valve if there is a flame up.

Faulty Junkers water heater

first find out from your manual what the flashing red light means...that should narrow your search---could be a thermocouple shot,a rubber diphragm in the gas valve has weakened and not operated, or gas pressure into the appliance may suddenly be too low, or springs in gas valve may have worn out---very many possibilities
