Alpha E60 Fault Code: Causes, Fixes & Repair Costs
What does the Alpha E60 fault code mean?
The E60 code on an Alpha boiler signals that the boiler's control board has detected a problem with the flue fan. This fan has two jobs: drawing fresh air into the combustion chamber and pushing the resulting exhaust gases safely out through the flue. Without a functioning fan, combustion gases could build up inside the appliance, so the boiler locks out as a precaution until the issue is resolved. You may notice the boiler attempting to start but cutting out quickly, or failing to fire at all.
General guidance only — not a substitute for professional advice. Any gas work must be carried out by a Gas Safe registered engineer. If you smell gas or suspect carbon monoxide, leave the property and call the National Gas Emergency line on 0800 111 999.
Common causes
- Faulty or worn fan unit Common
The fan motor itself is the most frequent culprit. Bearing wear over time can cause the motor to seize or run erratically, and the boiler's PCB detects the abnormal speed signal and triggers E60. An engineer can measure the fan's electrical resistance and speed feedback to confirm this.
- Blocked or obstructed flue Common
A nest, debris, or ice build-up blocking the flue terminal restricts airflow enough to affect fan performance. The fan may still spin but cannot move the required volume of air, causing the control board to flag a fault. Check the external flue terminal for any visible obstruction from outside — this is one check you can do safely yourself.
- Loose or damaged wiring to the fan Sometimes
Vibration over years of use can loosen the electrical connectors on the fan's harness, causing intermittent signal loss to the PCB. Corroded or chafed wires produce the same effect. An engineer will inspect all connections and the wiring loom during diagnosis.
- Burnt-out motor windings Sometimes
Prolonged use, power surges, or overheating can burn out the copper windings inside the fan motor, causing it to draw incorrect current or stop entirely. This is confirmed by resistance testing and almost always requires a full fan replacement.
- PCB (printed circuit board) failure Rare
If the fan itself checks out mechanically and electrically, the fault may lie with the control board that monitors and drives the fan. A faulty PCB may send incorrect voltage to the fan or misread the speed feedback signal, generating a false E60 code.
How to fix it
- Check the external flue terminal for obstructions DIY safe
Go outside and locate where the flue exits the building — usually a white or grey plastic terminal on an external wall or roof. Look for bird nests, leaves, ice, or anything blocking the opening. If there is a visible blockage you can safely reach, remove it. Do not dismantle any pipework or fittings.
- Listen to the boiler when it attempts to start DIY safe
Stand near the boiler and try to fire it up. A healthy fan produces a clear, consistent hum before the burner lights. No sound at all may indicate the fan has no power supply; grinding or rattling suggests mechanical wear. Note what you hear — this information is useful for the engineer.
- Reset the boiler once DIY safe
On most Alpha models, rotate the front selector dial to the RESET position and hold it there for approximately 30 seconds before returning it to your normal heating or hot-water setting. Allow the boiler a full startup attempt. If the E60 code returns immediately, do not reset again — repeated resets will not fix an underlying fault and may mask diagnostic information for the engineer.
- Check your boiler's warranty status DIY safe
Alpha boilers typically carry a 7–10 year warranty depending on the model and whether annual services have been carried out. If your boiler is still within its warranty period, contact Alpha directly before booking an independent engineer, as a warranty repair could be covered at no cost to you.
- Call a Gas Safe registered engineer to diagnose and repair Gas Safe engineer
If the fault persists after a single reset, a Gas Safe engineer must take over. They will test the fan motor's winding resistance and speed-feedback signal, inspect all wiring connections, check for flue restrictions that aren't visible externally, and test PCB output voltage to the fan. Only a qualified engineer should remove the boiler casing, handle gas components, or replace the fan or PCB.
Parts you may need
- Boiler fan / flue fan assembly (Alpha-compatible) · from £150
- Fan wiring harness / connector set · from £25
- PCB (printed circuit board) · from £280
The exact spare depends on your boiler's GC number (on the data badge). Check this against the part before buying.
Typical repair cost
Expect to pay roughly £225–£375, depending on the underlying cause.
Frequently asked questions
Is it safe to keep using my Alpha boiler while E60 is showing?
No. The boiler should already be locked out and refusing to fire, which is the correct safety response. The fan ensures harmful combustion gases are expelled through the flue — if it is not working properly, do not attempt to bypass the lockout or repeatedly reset the boiler. Leave it off and call a Gas Safe engineer promptly.
How much does it cost to fix an Alpha E60 fan fault in the UK?
Most homeowners pay in the region of £225–£375 for a fan replacement including parts and labour. The fan unit itself typically costs £100–£200 depending on the Alpha model, with labour and call-out adding the remainder. If the PCB also needs replacing, costs can rise to £400–£600 or more, at which point — especially on an older boiler — it may be worth comparing the repair quote against the cost of a new boiler installation.
Why does E60 keep coming back after I reset the boiler?
A recurring E60 means the underlying cause — worn fan bearings, a wiring fault, a flue blockage, or a PCB issue — has not been addressed. Resetting only clears the lockout temporarily; it does not fix the component that triggered the fault. If E60 returns after a single reset, stop resetting and book a Gas Safe engineer to diagnose the root cause.
My Alpha boiler is still under warranty — who should I call for E60?
Contact Alpha directly in the first instance. Alpha boilers typically carry a 7–10 year warranty (the exact term depends on the model and whether you have maintained annual services). If your warranty is valid, Alpha can arrange an approved engineer at no cost to you. Booking an independent engineer first could potentially affect your warranty claim, so always check your warranty status before proceeding.
