Alpha boiler repair
E-Tec and CD combi repairs and replacements. £99 fixed diagnostic inc VAT across Birmingham, the Black Country and the wider West Midlands — and a straight answer on whether yours is worth repairing.
Common faults
What goes wrong with Alpha boilers
E1 — ignition lockout
No flame detected. Gas supply, electrode or condensate blockage.
E10 — low water pressure
Pressure below minimum. Repressurise; persistent loss means a leak or failed vessel.
E3 — fan fault
Fan not reaching the required speed. Usually the fan or its wiring loom.
Hot water fluctuating
Scaled plate heat exchanger or a diverter valve on the way out.

Straight talk
Is your Alpha worth repairing?
Under ten years old, repair. Older Alpha 240/280 non-condensing units are inefficient and awkward for parts, so replacement usually makes better financial sense.
Fault codes
Alpha fault codes we see most
Low pressure
Pressure below 1 bar — heating won't run properly
Not an emergency, but a system losing pressure weekly is leaking somewhere. Get it found before it damages floors or ceilings.
Frozen condensate
Boiler locked out after a cold night
Often a DIY fix. If it refreezes every cold snap, get the pipework corrected properly.
Symptoms
Or start with what it's doing
Boiler losing pressure
A sealed heating system should hold roughly 1 to 1.5 bar cold. If yours keeps sliding towards zero, water is escaping somewhere — pressure does not simply evaporate.
Boiler leaking water
A leaking boiler is never something to leave. Water and electrics in the same casing means the PCB is on borrowed time, and a slow leak will rot the heat exchanger from the outside in.
No hot water
When the heating works but the taps run cold, the boiler is firing — it just is not sending the heat to the right place. That narrows the fault down to a handful of components.
Boiler keeps turning off
A boiler that lights and then shuts down within a minute or two is protecting itself. Something in the safety chain — flow, flame, pressure or airflow — is not happy.
Radiators cold at the bottom
Cold at the top and hot at the bottom means trapped air — bleed it. Cold at the bottom and hot at the top means magnetite sludge sitting in the radiator, and bleeding will do nothing at all.
Boiler making a banging noise
Boilers make noise, but they should not make new noise. A change in sound is nearly always the first warning that something is scaling, sticking or starving of flow.

Frequently asked questions
Do you repair Alpha boilers?
Yes. We work on E-Tec, InTec and CD ranges. Some Alpha parts need ordering in, so we'll confirm timescales on the diagnostic visit.
Are Alpha boilers reliable?
The E-Tec is a decent budget boiler with a strong guarantee. It won't match a Viessmann on longevity, but it's dependable when it's serviced annually.
How much is an Alpha repair?
Usually £130–£340 inc VAT, fixed price given before we start work.
