We've done dozens locally.

Local knowledge · Great Harwood (BB6)

What you should know about boiler repair in Great Harwood.

Most Great Harwood repairs we're called to start with the same three faults: F22 / low-pressure lockouts, F1 / F75 sensor errors, and sludge-related limescale on plate exchangers (160–200 mg/L mains accelerates this in BB6). We carry the most common Worcester, Baxi, Vaillant and Ideal parts on the van — 85% first-visit fix rate across Great Harwood on jobs booked before 11am.

We cover the whole Great Harwood area including Towngate, Glebe Road, Whalley Road, Park Lane, Mayfield Avenue, Queen Street, with same-day visits for repairs and a fixed-price quote within 24 hours for installations.

We live and work in this part of Lancashire, so local quirks (back-yard gas runs, listed-stone flue routes, BB6 mains pressure) aren't surprises.

Real jobs from Great Harwood (BB6). Names removed for privacy — we're happy to put you in touch with a reference customer in your postcode before you book.

Worcester EA lockout — Saturday 7am, Great Harwood

Got the call at 6.45am from a young family in BB6, no heat, baby in the house. EA fault = ignition lockout. Stripped the burner cover, found a coked-up flame-sense electrode and a partly-blocked injector. Cleaned, re-set the gas valve, ran a CO2 check — back on by 9.15am. £140 callout, parts swapped for £42.

Baxi E133 — dirty PCB connector

Baxi 800 combi in Great Harwood (BB6) throwing E133 (no flame detected) every couple of days, but resetting fine. We took the controls down and found a hairline crack on the flame-sense ribbon connector — moisture was creeping in from a slow boiler-cupboard leak. Soldered the connector, replaced the seal, gone 6 months without a recurrence.

Vaillant F.22 low-pressure puzzle

Repeated F.22 fault on a Vaillant ecoTEC from 2016 in Towngate. Filling loop wasn't to blame — system was holding pressure overnight. We pressure-tested the rads upstairs and found a hairline pinhole on the return tail of a bathroom towel rail. New TRV + tail kit, full re-flush, fitted a Magnaclean Pro 2. No callbacks since.

Common boiler repair issues · Great Harwood

5 boiler repair problems we fix most in Great Harwood

Every boiler repair job in Great Harwood (BB6) has its own pattern — but a handful of issues turn up over and over. Here's what we hit most often on boiler repair work in Great Harwood, and what we typically find:

Pressure dropping below 1 bar

The most common winter callout in Great Harwood. Usually micro-leaks, a tired PRV, or a flat expansion vessel. We carry pressure gauges, expansion vessels and PRVs on every van — first-visit fix in 85% of cases.

Worcester EA / Baxi E133 / Vaillant F22

Lockout codes from the big four manufacturers. Most are a dirty flame-sense electrode, a duff ignition lead, or a soft gas pressure. We stock OEM electrode kits for Worcester, Baxi, Ideal and Vaillant.

Diverter valve stuck

Hot rads but cold taps (or vice-versa). Diverter valve diaphragm gone or actuator pin seized. Replacement cartridge + o-rings, hour on the bench, done — typically £85–£120 parts.

Frozen condensate pipe

Lancashire winters bite — exposed white plastic condensate pipes freeze and lock the boiler out. Quick-fix with warm water, permanent fix with lagging or an internal re-route.

PCB / fan / pump failure on older boilers

On 10+ year boilers we see PCBs, fans and pumps fail in roughly that order. We diagnose with manufacturer kit (no guessing), swap from van stock for the big four brands, and tell you honestly when replacement is the better spend.

+Will I need a powerflush with my new boiler in Great Harwood?

If your current system is older than 10 years or you have any sludge symptoms — cold spots on radiators, banging/kettling, frequent blockages, dirty water when bleeding rads — a powerflush is almost always worth doing before a new boiler goes in.
