Junkers and Bosch boiler service in Naples
Service and repair of Junkers and Bosch boilers in Naples and across Campania. We are not the brand's official service centre. We are a qualified business that works on boilers from several manufacturers. If the display shows EA, CE or another code, we read it together, even on a video call, and work out whether a check is enough or you need a technician.
From €110 + VAT about 1 hourCleaning, flue gas check and logbook. Compliance sticker (bollino) is extra

Do not take the boiler apart and do not touch the gas or electrical parts: the reset is done only from the control panel. If you smell gas, do not press anything on the boiler, open the windows, go outside and call the distributor's emergency line from there.
Recognise the problem
- The display shows EA and the boiler does not light
- CE appears and the pressure gauge needle is low
- With C6 the boiler locks out while you can hear the fan running
- The reset works but the code comes back soon after
- You have a Junkers that is a few years old and do not know whether parts are still available
The most common causes
- 1
Flame not detected
The boiler opens the gas but does not see the flame: gas tap closed, gas arriving poorly, electrodes dirty or disconnected.
- 2
Low system pressure
With too little water in the circuit, the boiler stops and shows CE. If the pressure drops often, a leak has to be found.
- 3
Air and flue gases
The fan pushes the fumes out and a pressure switch monitors the airflow. If either one works badly, or the flue is blocked, C6 appears.
- 4
Electronics and sensors
Board, probes and wiring can develop faults over the years that no reset will clear.
What you can safely check yourself
- Read the code and photograph it, along with the rating plate
- See whether the gas tap handle under the boiler is in the open position and whether the kitchen burners light
- Read the pressure gauge before the boiler heats up
- If the manual allows it, use the reset button once and wait
- Check from outside that the flue terminal on the wall or balcony is not covered
Never open the boiler or the gas water heater, and always switch off the power before touching an electrical appliance. If in doubt, call us.
When you need a technician at home
- EA returns with the gas on and normal
- CE reappears a few days after topping up
- C6 stays even after the reset
- The boiler shows codes linked to probes or the board
- Servicing or the flue gas check is due

Most common error codes on Junkers and Bosch boilers
EA, flame not detected: the boiler cannot light or recognise the flame. Bosch gives as first checks the gas tap being open, which you can confirm with the hob, and the water pressure. If all is in order, the fault is in a component.
CE, low system pressure: there is little water in the heating circuit. Bosch says to bring the pressure back to about 1.2 bar. If the code stays, you need a technician.
C6, insufficient airflow: the boiler cannot guarantee the air passage it needs. The parts involved are the fan, the pressure switch and the board, and these are not checks you can do as a user.
Codes and procedures change between series and production years, and on some models a number is added to the code. That is why we always start from the rating plate and the manual for your boiler.
Junkers is now called Bosch
Junkers has been part of the Bosch group since 1932, and in Italy, since September 2018, the brand has been integrated into Bosch. For this reason many boilers installed as Junkers now have a Bosch equivalent.
Bosch itself states that the technology of Junkers products stays the same, that owners do not have to replace them and that it continues to make parts for earlier models. When a part is needed, we start from the product code written on the rating plate.
Junkers and Bosch out of warranty
We are not an official Junkers or Bosch service centre. We repair these boilers like the others, as a business qualified under DM 37/2008 for heating and gas systems, with parts chosen according to the model.
If the boiler is still under warranty, read the manufacturer's conditions first. Out of warranty, a repair in the Naples area generally costs between €40 and €250 depending on the fault. The precise price comes after the diagnosis, before we start.
Want to know what it is first? Show us
You show us the display, the pressure gauge, the rating plate and the gas tap under the boiler. We tell you what the code means on your model and guide you through the checks you can do, such as topping up the pressure or the reset the manual allows. If the fault involves the flame, the fan or the board, we prepare the visit and deduct the €9.90.
Video consultation, up to 15 minutes: €9.90 (€14.90 on Sundays), deducted from the bill if we then come to your home.

Frequently asked questions
What does EA mean on a Junkers or Bosch boiler?
That the boiler has not detected the flame. Check that the gas tap is open and that the water pressure is right, then try a reset. If the code returns, the ignition needs checking.
Can code CE be solved on my own?
Often yes: it is enough to bring the system pressure back to the stated value, about 1.2 bar according to Bosch. If it drops again, there is a leak or a problem with the expansion vessel, and you need a technician.
Do you still repair older Junkers boilers?
Yes, we work on Junkers and Bosch boilers of different ages. For older models we first check whether parts are available, so you know straight away whether repairing or replacing makes more sense.
Are you the official Bosch service centre?
No, we are not the brand's official service centre, either for Bosch or for Junkers. We are a qualified business that repairs boilers of several brands.
What should I prepare for the video call?
A photo of the rating plate, the code on the display and a shot of the pressure gauge. If you can, keep the boiler manual nearby too.
