    SABRE (VOKERA) HE 25 COMBI IS LEAKING WATER

    Hi, My 5 year old Sabre HE 25 combi is leaking water. I have attached the picture. Not pouring out, but it is leaking. Pressure drops from 1.5 bar to zero bar fairly quick, hence the red light comes on and it does not fire. The water comes out from the drain pipe under burner...

    Sabre (Vokera) 25HE No Hot Water nor Central Heating working

    Sabre HE25 was working but cutting out now and then and red light coming on. I used to reset it, it then worked again. It went like this for few months. Recently, after I came back from holiday the other day, it stopped firing up all together. Pump runs, no red light comes on, infact...

    Sabre (Vokera) 25HE No Hot Water nor Central Heating working

    I got it fired up AGAIN by fiddling with the speed of the pump as the tap is running. (C/h switched off). Once it fires up, it works non stop as long as the hot water tap is on. When you turn the tap off, it may not work next time you demand hot water. It is too much of a coincidence...

    Sabre (Vokera) 25HE No Hot Water nor Central Heating working

    No, as turned on the hot water tap, just before the stage it normaly fires, it cut out again and the solid red light is on. I am back to square one :( To Agile: - No, it was working (on and off with the fault) before I change the DWH sensor. I guess, the only other thing happened...

    To BB, I have a SABRE 25 HE. Here are the sensors I have changed. As we agree, the one on the left is Primary NTC sensor, and the other one is DHW sensor (secondary sensor?) which I have just changed. If you look at the DHW sensor closely, you will notice the greenish deposits...

    To DP, Thank you for taking your time and writing. I do understand the principle of how the combi boiler or CH systems works. However, I do not have knowledge and special equipment necessary for checking and eliminating the components in order to diagnose fault like the qualified...

    Sabre (Vokera) 25HE No Hot Water nor Central Heating working

    Thank you for all your replies. I am getting confused now. According to user manual, Solid Red Light fault indicates to NTC Primary Sensor and it is supposed to be fixed (screwed) on the right hand side of the main heat exchanger. I bought pair of sensors pictured below. I have...

    Sabre (Vokera) 25HE No Hot Water nor Central Heating working

    Thanks very much GG, I will follow your instructions tomorrow and will post the result. Just for clearity, you do want me to remove and bin the "DHW flow regulator" and run the system without this component? This means main water supply in to combi has to be by passed with something which...

    Hi GG, I have already replaced Primary NTC Sensor = Primary Thermistor? The one you screw in with 13mm socket/spanner, on the righthand side of main heat exchanger. Is this primary thermistor? However, I could not find Domestic Hot Water flow regulator and Secondary Thermistor in my...

    Hi BB, Thanks for pointing out the ignition board. Since I have managed to start it yesterday, combi has been working fine although I know it will cut out again soon, as it did in the past. Considering the new information above would you still say the faulty part is the ignition...
