Bitron PCB Sime Praktica HE 25
The control PCB governs the ignition, burner modulation, pump, and safety features of the boiler in the Bitron Sime Praktica HE 25. If it fails, you will notice that the boiler does not start, locks out, or behaves erratically, potentially displaying faults such as AL 88, AL 98, or AL 99. This part is compatible with the Praktica HE 25, Praktica HE 30, Murelle One HE 25, Murelle One HE 30, Vera HE 25, and Vera HE 30 models, among others. It is advisable to replace it when it shows faults or recurring errors.

How to check if the part number 6324950 is the one for your boiler.
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 6324950. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB 6324950 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not respond to any commands from the remote control or the panel, as if it were disconnected.
Cause: The PCB is responsible for receiving and executing the ignition commands; if it is faulty, the boiler does not respond.
Check that the boiler has electrical and gas supply before considering the PCB responsible.
- 02
The same fault code always appears, and resetting the boiler does not clear it.
Cause: The PCB locks the unit for safety when it detects an out-of-range condition and keeps the lock until the cause is resolved.
Look for the exact code in the boiler manual: it may refer to a sensor or external component, not necessarily to the PCB.
- 03
The boiler turns off and on by itself repeatedly, without anyone touching the thermostat.
Cause: An intermittent fault in the control board causes micro-cuts that reset the control cycle.
Note if the power outages coincide with the use of domestic hot water, with heating, or with both; this helps to narrow down the source.
- 04
The boiler operates erratically: it modulates randomly, changing power without any change in demand.
Cause: The PCB manages the modulation according to the readings from the sensors; if it misinterprets those signals, the power varies without reason.
Confirm that the temperature sensors are not loose or poorly connected before attributing the fault to the control electronics.
Fault codes for Sime that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| AL 88 | Internal error (protection of a component on the PCB) | The PCB itself activates its internal protection due to component failure or overcurrent; it is usually resolved by replacing the PCB. Check power supply voltages, ground connections, and board connectors beforehand. |
| AL 98 | Software error, card start-up | The PCB does not complete the firmware boot due to software corruption or microcontroller failure. Check reset/power cut and stable power supply; if it persists, replace the board. |
| AL 99 | Generic fault of the card | The PCB self-diagnosis detects a non-specific fault on the board. Check voltages and connections; if the error repeats after reset, replace the PCB. |
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.
