Remeha H.01.07 Fault Code: Causes, Fixes & Repair Costs
What does the Remeha H.01.07 fault code mean?
H.01.07 is a fault code appearing on Remeha boilers — most likely within the Quinta ACE or similar commercial range — that signals an abnormal operating condition requiring the boiler to shut down safely. The 'H' prefix on Remeha equipment typically indicates a model-specific or system-level fault, and the .01.07 sub-designation points toward an ignition, gas supply, or combustion-related issue within that fault family. The boiler will stop firing and lock out until the underlying problem is identified and resolved. Because H.01.07 is not publicly documented in Remeha's consumer-facing materials, the most reliable next step is to contact Remeha technical support on 0330 678 0140 with your exact model and the code displayed, or to book a Gas Safe registered engineer to diagnose the boiler in person.

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
- Ignition or flame detection failure Common
The boiler attempted to light but could not establish or hold a stable flame within the permitted number of tries, triggering a safety lockout. This can be caused by a worn ignition electrode, a contaminated flame-sensing electrode, or a weak spark. It is the most frequent underlying cause behind 'H' series lockout codes on Remeha commercial units.
- Interrupted or low gas supply Common
If the gas pressure at the boiler falls below the required level — due to a supplier interruption, a partially closed service valve, or high demand across the building — the burner will fail to light and the boiler locks out. Checking whether other gas appliances in the property work normally is a quick first indicator.
- Frozen or blocked condensate pipe Common
In cold weather the plastic condensate pipe that carries acidic waste water to a drain can freeze solid, causing the boiler to shut down. This is a particularly common winter fault on any condensing boiler and is one of the few issues a homeowner can safely address themselves.
- Gas valve fault or blockage Sometimes
The gas valve may be sticking, partially blocked, or failing electrically, preventing the correct volume of gas from reaching the burner. A related code in the same Remeha family — H.02.10 — is specifically documented as a blocked or defective gas valve, suggesting this fault family is closely associated with gas valve behaviour.
- PCB or control board fault Sometimes
The main printed circuit board coordinates ignition timing, gas valve operation, and flame supervision. A failing PCB can generate spurious lockout codes including those in the 'H' series — a user-reported case of the related code H.02.05 on a Remeha Ace required a complete circuit board replacement.
- Flue or combustion air obstruction Sometimes
A blocked or partially obstructed flue terminal, or a fault with the combustion fan, can prevent adequate air supply or exhaust clearance, causing the boiler to lock out on a combustion safety check.
How to fix it
- Check that other gas appliances in the property are working DIY safe
Turn on a gas hob ring or check another gas appliance. If nothing is working, the issue is likely a supply interruption — contact your gas supplier before calling an engineer.
- Check the boiler's system pressure DIY safe
Look at the pressure gauge on the boiler front. It should read between 1.0 and 1.5 bar when the system is cold. If it is below 0.8 bar, top it up using the filling loop following the instructions in your boiler's user guide. Do not exceed 2.5 bar.
- Inspect the condensate pipe for freezing (winter months) DIY safe
Locate the white plastic condensate pipe that exits the boiler and runs to an external drain or internal waste pipe. If it feels solid or you can see ice around it, thaw it carefully using warm (not boiling) water poured along its length, or wrap it in a warm cloth. Once thawed, attempt a reset.
- Reset the boiler once DIY safe
Press and hold the reset button as described in your boiler manual. Allow the boiler to complete its full ignition cycle — this can take up to two minutes. If it lights and runs normally, monitor it over the next few hours. Limit resets to two or three attempts; repeated resetting without fixing the underlying fault can mask a serious problem.
- Do not attempt to inspect or adjust gas components Gas Safe engineer
Working on the gas valve, burner assembly, ignition electrodes, flue, or any internal gas-carrying component requires Gas Safe registration. These parts must only be inspected and serviced by a qualified engineer.
- Do not attempt PCB or wiring repairs Gas Safe engineer
The control board and associated wiring harness involve both mains voltage and gas control signals. Any intervention here must be carried out by a Gas Safe registered engineer with the appropriate Remeha technical training.
- Contact Remeha technical support or book a Gas Safe registered engineer Gas Safe engineer
If the boiler has not recovered after the homeowner checks above, call Remeha technical support on 0330 678 0140 with your exact model name and the fault code shown on the display. Alternatively, book a Gas Safe registered engineer to attend, diagnose, and carry out any necessary repair. Because H.01.07 is a model-specific code not publicly documented, an engineer with access to Remeha's service documentation will be best placed to resolve it accurately.

Frequently asked questions
What does the H prefix mean on a Remeha fault code?
On Remeha commercial and Quinta ACE range boilers, the 'H' prefix typically indicates a model-specific or system-level fault condition that has caused the boiler to lock out for safety. Unlike the more common 'E' series codes used across Remeha's residential range, 'H' codes are associated with newer commercial platforms and often relate to gas supply, combustion, ignition, or PCB control issues. Because these codes are not publicly documented in consumer-facing materials, you will generally need to either contact Remeha on 0330 678 0140 or have a Gas Safe engineer consult the official service manual for your exact model.
Can I reset a Remeha H.01.07 fault myself?
Yes, a single reset attempt is a reasonable first step and is safe for a homeowner to carry out. Press the reset button and allow the boiler to complete its full start-up cycle. If it lights and runs normally, monitor it closely over the next day. However, if the boiler locks out again — or if you need to reset it repeatedly to keep it running — stop and call an engineer. Repeated resets without fixing the root cause can mask a developing fault and, in the case of gas-related issues, could be unsafe.
How much does it typically cost to repair a Remeha H.01.07 fault?
For the most common underlying causes — ignition electrode replacement, gas valve servicing or replacement, or fan repair — most homeowners pay in the region of £150 to £400 including parts and labour. A straightforward ignition component replacement at the lower end of that range, or a gas valve swap at the higher end, are the typical scenarios. If the fault turns out to involve the main PCB or control board, costs can rise to £400–£600 or more depending on the model, and a heat exchanger failure on a commercial unit can exceed that further still. Getting a diagnosis visit first (usually £50–£80) before committing to a repair is always advisable.
Is H.01.07 related to the Remeha H.02.05 or H.02.10 codes?
They appear to be part of the same fault code family used on Remeha's commercial and Quinta ACE range. H.02.10 is documented as relating to a blocked or defective gas valve, while H.02.05 has been reported in connection with a PCB failure requiring a circuit board replacement. H.01.07 sits in the same alphanumeric series, suggesting a related but distinct sub-fault — possibly in the ignition or combustion monitoring area. Because the precise definition of H.01.07 is not publicly available, an engineer with access to Remeha's technical documentation is the only reliable source for a definitive answer.
