Combi Boiler 3-Way Valve Stepper Motor 220V 31600001 (Baymak, Baxi, ECA Compatible)

It is the most important electromechanical part of the hydraulic group that provides the switch between the central heating installation and domestic water (tap water) in combi boiler systems. It is a high-quality 3-way valve (stepper) motor that definitively resolves the fault in the complaints frequently encountered by service technicians in the field, such as "the radiators heat up when the hot water is turned on" or "the combi boiler does not supply hot water". It works in full compatibility with many brands, primarily Baymak, Baxi and ECA.

• Wide Compatibility: It can be mounted directly onto the composite valve blocks (hydraulic groups) of many brands such as Baymak, Baxi, ECA, Airfel, Biasi, Termet, Kentatsu, Fondital and Riello.
• Connection Design: It has a standard 3-pin (socket) plug-and-play electrical connection and a clip-type latch design for easy installation.

Installation of the 31600001 Valve Motor and Technician Tips

• Before fitting the new stepper motor, be sure to check the push-rod seat in the combi boiler's brass or composite hydraulic block (valve body). If there is water leaking (dripping) out of the shaft or the O-ring, this water will enter the motor directly and cause the new part you have fitted to burn out in a short time as well. The priority is always to stop the water leak.
• When seating the motor during installation, make sure that the retaining clip or latches are fully locked; otherwise the motor may come out of its seat with its own 70N thrust.
• To make sure the old motor is completely faulty, you can easily test with a multimeter whether a 220V voltage command is coming from the electronic board to the socket terminals by switching the appliance from winter to summer mode.

Frequently Asked Questions

What does a combi boiler 3-way valve stepper motor do?

The 3-way valve stepper motor is the electromechanical part of the hydraulic group that provides the switch between the central heating installation and domestic water (tap water) in the combi boiler. It operates at 220-240V 50/60 Hz, has a 70N thrust and a T70 temperature rating class; it can be mounted directly onto the hydraulic groups of brands such as Baymak, Baxi and ECA, as well as Airfel, Biasi, Termet, Kentatsu, Fondital and Riello.

Which fault symptoms call for replacing the 3-way valve motor?

The two most common symptoms in the field are the radiators heating up when the hot water is turned on and the combi boiler not supplying hot water. In these complaints, the source of the fault is usually the 3-way valve stepper motor, and replacing the motor solves the problem.

What are the equivalent and OEM codes of the 31600001 stepper motor?

Reference and OEM codes: 31600001, 7100473, 720064401, 710047300, 6087329, 6319620, BI1431100, 7006907245, Z1480.01.05.00, 1.028572, 7022420004, 6ATTCOMP00, 20024841, 4366913, 6120302. If the code of the part you have is in this list, the product can be used directly as an equivalent.

What should be considered when mounting the stepper motor?

Before fitting the new motor, be sure to check the push-rod seat in the combi boiler's brass or composite hydraulic block; check whether there is water leaking from the shaft or the O-ring. Since the motor has a standard 3-pin socket plug-and-play electrical connection and a clip-type latch design, installation is practical.
