Exact diagnostics before any part is replaced
We diagnose conventional, combi and condensing wall-hung gas boilers. The error code is only a starting point: power, sensors, water circulation, combustion sequence and operating conditions must be checked before the cause is confirmed.
Ignition and flame faultsNo spark, no gas ignition, flame loss or repeated lockout.
No heating or no hot waterDiverter valve, flow sensor, plate heat exchanger or circulation fault.
Pressure and leakage problemsExpansion vessel, safety valve, automatic air vent or internal leak.
Pump and circulation faultsStuck pump, capacitor, relay, air lock or blocked system.
Fan and flue-safety faultsFan, pressure switch, venturi, condensate or exhaust restriction.
Electronic controlsPCB power supply, relays, connectors, sensors and control signals.

Correct connections, startup and settings
A new boiler must be matched to the system and commissioned correctly. We install replacements and new wall-hung boilers, check the water and gas connections, fill and vent the system, set operating parameters and test heating and domestic hot water.

- Mounting and hydraulic connection of the new unit
- Flue and condensate arrangement where required
- System filling, air removal and pressure check
- Startup, temperature settings and operating test
- Clear handover and basic user instructions
Instantaneous gas water heaters
Gas column repair and installation
We service compact wall-mounted gas water heaters that heat water as it flows — commonly called gas columns. These appliances have a different hydraulic and combustion layout from a heating boiler and require their own diagnostic process.
ARISTONBOSCH · BAYMAKDoes not ignite
Battery or power supply, microswitch, flow sensor, ignition unit, electrodes or gas valve.
Water is not hot enough
Scale in the heat exchanger, weak water flow, burner contamination or incorrect gas/water adjustment.
Flame is unstable or switches off
Draft, overheating, flame detection, gas pressure or blocked heat-exchanger fins.
Water leaks from the appliance
Water block, diaphragm housing, connections or damaged heat exchanger.
Replacement and installation
Mounting, water and gas connections, flue connection, leak checks and safe startup.
Safety first: if you smell gas, close the gas valve, ventilate the room, do not operate electrical switches and contact the gas emergency service.
