Radiators not working but hot water is. the little box on the wall (dont know what its called is just flashing red) I have pressed the reset buttons on there but nothing has happened
Please help

ormus

does a F code come up on the display panel?

Radsteral

check the pressure gauge or digital gauge ..whats the pressure now? if under 1 bar then it will not warm and you ll need to top up system with water to raise pressure.. if no pressure then some water has escaped ie, leak or you just removed couple of radiators and when you removed radiators and when you put them back the system s pressure falls

lollol

@ormus no F on any panels that I can see
@Radsteral the bar is in the grey area. Have not done anything to radiators.
Is it eaSy to top up the water?

ormus

light grey or dark grey?

light grey means the pressure is too low.

I have one of these boilers. There are three water pressure zones where it says bar on the dial, a small white zone first, then a large grey zone and finally a smaller red zone where the water pressure should never be.

The water pressure gauge should be about half way in the grey zone. My fitter put a mark on it showing the ideal pressure when the system is operating. The water pressure will increase when the water is hot so it needs to be just below half way. It's easier to increase the pressure than lower it so remember that.

However, these boilers don't work if the pressure is in the white zone, the hot water will not work and they show an F code on the LCD display.

To fill the system with more water there are two levers on the bottom of the boiler, underneath. If you feel with your hand underneath the boiler there are two large holes with the handles. They are like (-) and the - needs to be turned. The left one first needs to be turned as far as it will go and that allows the system to be filled. The system is filled by then turning the right dial. You will hear water flowing. Turning the dial back to cut the water flow off when done. Monitor the pressure gauge while doing it and remember to keep the pressure at about 1/3 in the grey. Turn the right dial off and then do the same with the left dial - remember to turn the left dial to seal the water off!

If it starts to function, leave it to warm up and check the pressure again. It should be just over half way in the grey. The real system pressure can be seen in the LCD display if you press the - button below the LCD display.

If it's in the grey area like you say, the water pressure is okay and it shouldn't stop the boiler from working.

Has the pilot light gone out? It will show something in the display to show that it is out. The pilot light button needs to be pressed to re-ignite the boiler if it's out. Wind can blow it out on rare occasions.

I don't think there is a lot more you can do.

Thank you all @ a.penny.saved does the flashing red light on the wall siemens box mean anything.

Find the instructions on line or wherever you have filed them and see what it says.

At a guess from behind a screen with info provided I would say it's a wireless stat that has lost communication with the receiver.
Re bind the pair or it's faulty.

New battery?

Ignore all the other posts - they obviously haven't read your post properly. By the way, @a.penny.saved, this boiler is a modern A rated boiler and doesn't have a pilot and can't be blown out by the wind.
I'm not familiar with the Siemens controls but I suspect yours has lost comms with the transmitter (presuming it's a wireless thermostat). If I remember correctly, the receiver (bit by the boiler) has TEST and LEARN buttons on the back. Press them together then press the reset button on the transmitter (bit on the wall in another room). You will probably lose any settings and have to reprogramme the sender. If you can find the model number (front of the sender) you should be able to Google for the manual.

EDIT:Ignore all the other posts - apart from Canucklehead

If you have a battery operated wireless programmer, it's probably that the batteries are flat.........

i m inocent;) im just a plasterer..but have had to learn the boiler well, since th plumber who fited it left it in a mess, with couple of coper pipes leaking water and boiler having not enough pressure.
the book that comes with the boiler would help if you spend a bit of to read it .
my one is similar to yours but only more powerful
if pressure gauge is to the white area, then no pressure, if on the grey is fine if on the red- runn for your life;)
if its in grey zone then look for diferent problem, ie, thermostat s duracell bunnies have died
