How to check if the ref. 05733000 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 05733000. 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 plate heat exchanger 05733000

The plate heat exchanger transfers heat to the domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The water comes out in bursts of hot and cold without anyone touching the faucet.

  Cause: The heat exchanger has the internal passage partially blocked by limescale, which causes the domestic hot water flow to be inconsistent.

  Check if the problem occurs only with the minimum flow of the tap; often the obstruction is more noticeable when it is opened slightly.

• 02

  The hot water comes with low pressure compared to the cold water.

  Cause: The limescale buildup on the plates reduces the flow area of the domestic hot water circuit.

  First, rule out a dirty aerator or filter in the faucet before assuming it is the heat exchanger.

• 03

  The heating pressure gauge shows lower pressure each week without visible leaks.

  Cause: An internal leak between plates allows the water from the heating circuit to pass into the domestic hot water system.

  Check if the water consumption in the house has increased without explanation; along with the drop in pressure, this points to a leak.

• 04

  You notice that the hot water comes out with a different tone or sediment than usual.

  Cause: When the plates give way, the water from both circuits mixes inside the heat exchanger.

  If you see this change, stop using hot water for consumption until you check the part.

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.
