How to check if ref. 6PROATTT00 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 6PROATTT00. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms that require diagnosis in the 3-way valve 6PROATTT00

The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The boiler does not switch between heating and domestic hot water.

  Cause: The actuator does not move the valve to the end of the opposite circuit.

  Check if the motor tries to move (buzzing or slight vibration) when requesting domestic hot water; if it doesn't move, check the power supply to the actuator.

• 02

  Noise or blockage in the 3-way valve motor

  Cause: The internal mechanism of the actuator is jammed or the gears are worn out.

  With the boiler turned off, try to move the actuator arm by hand; if it is very stiff, check for scale or dirt in the gas valve.

• 03

  The valve does not complete its travel and gets stuck halfway.

  Cause: The actuator loses strength or becomes decoupled from the shaft before reaching the end.

  Check that the actuator is properly fitted onto the valve shaft, without any play, before replacing it.

• 04

  The actuator gets very hot or smells burnt.

  Cause: The motor is straining against a stuck valve and is suffering from overexertion.

  Before changing the actuator, check that the valve turns freely by hand; if it is stiff, the problem may be with the valve, not the motor.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
