How do you open a filling loop?

How do you use a boiler filling loop?

2. Turn one valve so that it matches the direction of the pipe.
3. Slowly turn the other filling loop valve.
4. Water should start to come through the system.
5. Once it hits 1.4 bar, close both of the valves back up.

How do I find the filling loop on my boiler?

Identify the filling loop. Identify the pressure gauge. Turn the filling loop isolation handle 90 degrees, at this point you will hear water entering the central heating system (some filling loops have 2 handles, turn both handles 90 degrees)

Does a system boiler have a filling loop?

Most combi and system boilers require a pressure of 1 – 1.5 bar in order to operate. Open the valve or valves on the filling loop. You should hear the sound of rushing water – the system is filling up. You should also see the needle on the pressure gauge rise.

How do I fix error code F72?

The process to clear the fault code is simple:

1. Employ a qualified gas engineer.
2. Isolate the problem to limescale build-up.
3. Replace the thermistors.
4. Dose the heating system with inhibitor (to break down limescale)
5. Fit a scale reducer (a filter to catch limescale deposits)
6. Reset the boiler to clear the F72 fault code.

Why does my Vaillant turbomax run out of gas?

If the pipe runs outside, pour hot water over the pipe to defrost it, or place a bucket under the boiler and disconnect the plastic waste pipe on the far right of the boiler, before draining the condensate into the bucket. This fault, particularly common for the Vaillant Turbomax, is caused by a faulty ignition, or no gas getting to the boiler.

What does code F75 mean on Vaillant boiler?

Once the pressure returns to 1.5 bar, close the levers and reset the boiler. If the code F75 is flashing in your display, the fault is most likely to do with the boiler’s sensor not being aware that the pump has started running – so failing to notice a change in pressure.

Which is the most common fault in a Vaillant boiler?

Common Fault 4: Code F28 (Vaillant Turbomax) This fault, particularly common for the Vaillant Turbomax, is caused by a faulty ignition, or no gas getting to the boiler.
