The Junkers Eurostar ACU HIT ZWSE 28 4 MFA manometer is a device that measures and controls the pressure of the boiler circuit. Its function is essential to ensure that pressure and temperature are maintained at the appropriate levels. When it fails, you will notice incorrect readings, which can cause the boiler to lock out due to a false lack of pressure or not regulate the temperature properly. This manometer is compatible with boilers from the Eurostar ACU HIT range and specific models of Cerastar B50 ZWSE, among others. It is recommended to replace it when you experience those symptoms of malfunction.

Guide

How to check if the ref. 87167618750 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 87167618750. 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.
Diagnosis and fault codes

Symptoms and faults that the manometer 87167618750 solves.

The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The needle is outside the green zone even though you have replenished pressure in the circuit.

    Cause: The mechanism may be misaligned and no longer indicates the same as the actual pressure of the system.

    Compare the reading with the feel of the filling valve or with a portable manometer if you have one.

  • 02

    The pressure gauge does not move or gets stuck regardless of what happens with the installation.

    Cause: The internal shaft seizes over the years and stops transmitting any pressure changes.

    Bleed a radiator and check if the needle follows the drop; if nothing moves, the fault is in the pressure gauge.

  • 03

    The reference green zone is not distinguishable due to wear on the glass or the dial.

    Cause: The plastic of the glass becomes opaque with heat and time, covering the colored strip that indicates the correct range.

    With good light or a flashlight, check if it is at least possible to see whether the needle is to the left or right of the green band.

  • 04

    The boiler is losing pressure and you need to check it visually.

    Cause: A reliable manometer is the reference to know if it is really necessary to refill water or if the problem is something else.

    Mark the current reading and check it a few hours later; if it decreases steadily, there is a real leak, not just a faulty pressure gauge.

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.
