Quick answer

Baxi E.01.17 is a permanent fault on the Platinum iPlus: the boiler sees no water circulation and stops. The manual allows a reset once the cause is removed. If the code returns, stop and call the official technical service.

Safety first

Stop and check this first

  • If you smell gas: no flames, no bells or switches, shut off the gas if that feels safe, open windows and get everyone out. Once outside, call your gas distributor's emergency line or 112.
  • This is a permanent lockout: resetting over and over does not cure a lack of circulation and may hide overheating. One reset is your limit.
  • Do not touch the pump, the wiring or the probes, and do not open the boiler casing. Those checks belong to an authorised technician.

Safe checks you can perform

  • Confirm the code and the colour of the control panel
  • Read the circuit pressure on the home screen
  • Reset the boiler one time only

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Check pressure, circulation and degassing
  • Do not attempt this professional task: Test the pump and probes before replacing parts
  • Do not attempt this professional task: Reset and confirm the code stays away

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Check pressure, circulation and degassing

    What they doAn authorised technician reviews the installation pressure, the circulation through the boiler and the system and, if needed, runs a manual degassing cycle.

    They must show youthe pressure they measured and how they confirmed the water moves.

    In writingthe checks performed and the result of each.

  2. Test the pump and probes before replacing parts

    What they doIf pressure and air do not explain the fault, the technician tests the pump and the temperature probes and their connections.

    They must show youthe measurement or test that justifies replacing the pump or a probe.

    In writingthe part replaced, its reference and the warranty.

  3. Reset and confirm the code stays away

    What they doAfter fixing the cause, the technician resets the boiler and leaves it running to confirm E.01.17 does not return.

    They must show youthe boiler running without the code after the reset.

    In writingthe cause found and the date of the repair.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Confirm the code and the colour of the control panel

    No special tools

    Who:
    you, no tools.
    How:
    Press the rotary knob to read the code and its description, and note the colour of the control panel.
    Result that matters:
    The manual links flashing red to a permanent lockout, so you know it is E.01.17 and not another fault from the same family.
    If you see E.01.17 with the panel flashing red, go on to read the pressure.
    If a different code appears, look up that specific code instead of following this page.
    Evidence to keep:
    A photo of the display with the code and of the panel colour.

  2. Read the circuit pressure on the home screen

    No special tools

    Who:
    you, no tools.
    How:
    On the home screen, the bar icon shows the current water pressure in the heating circuit. Compare it with what the manual asks when the system is cold. Note that the manual prints decimals with a comma.
    Result that matters:
    The manual recommends between 1,5 and 2,0 bar cold and says to refill below 0,8 bar.
    If the pressure is in that range, add no water and go on to the single reset.
    If it is lower, open the filling tap very slowly as the manual asks and close it once the range is reached; if the pressure keeps falling, stop refilling and call Baxi's technical service.
    Evidence to keep:
    A photo of the screen with the pressure value before and after.

  3. Reset the boiler one time only

    No special tools

    Who:
    you, one attempt.
    How:
    Once the pressure is right, hold the rotary knob down for 2 seconds, as the manual describes for permanent faults. Do not chain further attempts.
    Result that matters:
    The fault clears and the boiler restarts, or E.01.17 appears again.
    If it clears, note the date and keep an eye out in case it returns.
    If it comes back, stop there:
    do not reset again and call an authorised technician.
    Evidence to keep:
    A photo of the display after the reset and the time of the attempt.

What it means

The user manual for the Platinum iPlus and MAX iPlus (in Spanish only) lists E.01.17 as no water circulation, permanent. It is a permanent fault: the boiler stops and only starts again when reset after the cause is gone. Baxi's table points to insufficient circulation (pressure, degassing, pump) or a temperature probe error, but the code does not prove that any of those parts is faulty.

Warnings and stop conditions

  • Higheditorial warning

    If you smell gas: no flames, no bells or switches, shut off the gas if that feels safe, open windows and get everyone out. Once outside, call your gas distributor's emergency line or 112.

Symptoms and causes

Probable causes · in order

  • Low system pressureCommon

    Baxi's table tells the engineer to check the installation pressure for this fault, and too little pressure can leave the circuit without the water it needs to circulate.

    Evidence: Baxi Platinum iPlus y Platinum MAX iPlus, instrucciones de funcionamiento y mantenimiento para el usuario 7847811

  • Trapped air slowing the waterPossible

    One of the table's checks is to run a manual degassing cycle, which suggests trapped air may hold circulation back.

    Evidence: Baxi Platinum iPlus y Platinum MAX iPlus, instrucciones de funcionamiento y mantenimiento para el usuario 7847811

  • A pump that is not performingPossible

    The table includes checking the pump's operation. A technician has to measure it; the code alone does not say the pump is broken.

    Evidence: Baxi Platinum iPlus y Platinum MAX iPlus, instrucciones de funcionamiento y mantenimiento para el usuario 7847811

  • A temperature probe or its connection reading wronglyPossible

    The second block of the table covers checking the temperature probes and their connection: a wrong reading can make the boiler believe no water is moving.
