Sime Planet HE 25 ERP PCB Ref. 6324920
The Sime Planet HE 25 ERP PCB Ref. 6324920 is the component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it malfunctions, the boiler may fail to start, lock out, or operate erratically. This issue may be associated with faults such as ALL 88, ALL 98, ALL 99, ALL 77, or ALL 78. It is installed in models from the Brava Slim HE and Planet HE ranges, such as the Brava Slim HE 25, Planet HE 25, among others. It is recommended to replace it upon noticing any of the mentioned symptoms.

How to check if ref. 6324920 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 6324920. 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 6324920 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 doesn't turn on at all: neither the display nor the indicators.
Cause: The PCB distributes power to all the circuits; if it fails, the boiler becomes completely inoperative even if electricity reaches it.
Before replacing it, check the F1 fuse on the control board (visible on the label) and the circuit breaker of the installation; a blown fuse looks the same as a dead PCB.
- 02
A fault code appears on the screen that does not disappear after resetting.
Cause: The PCB locks the equipment when a safety reading doesn't match, even if the origin is from an external sensor.
Write down the exact code and check it before purchasing; depending on the model, some codes refer to a different component of the PCB.
- 03
The remote control or the thermostat cannot get the boiler to start.
Cause: The order reception stage of the PCB can fail in isolation, without affecting other functions of the equipment.
Check the thermostat wiring at its connector and the remote control batteries before replacing the PCB.
- 04
The boiler turns off sporadically on its own, without prior warning.
Cause: An intermittent fault in a component of the PCB (soldering, capacitor) causes interruptions that do not follow a fixed pattern.
Note when it shuts off (start-up, normal operation, with domestic hot water) to rule out other causes before deciding to replace it.
Fault codes for Sime that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| ALL 88 | Internal error (component protection on the board). | The PCB enters protection mode due to an internal hardware fault. Check voltages 230V/5V/12V on the PCB and isolate peripherals; if it reappears after reset/autocalibration, replace the PCB. |
| ALL 98 | Software error, card start-up. | The microcontroller on the PCB does not complete the boot. Try reset and auto-calibration; check for stable power supply and, if the issue persists, reprogram or replace the PCB. |
| ALL 99 | Generic fault on the PCB. | The PCB self-diagnosis detects a non-specific fault. Check the power supply and disconnect loads; if the error persists, replace the PCB. |
| ALL 77 | Maximum/minimum absolute limits error of current EV2 SGV. | The driver stage of the board that controls the EV2 modulator delivers current out of range. Measure signal/current to the modulator and wiring; if the EV2 valve is OK, the probable cause is the PCB. |
| ALL 78 | EV2 SGV upper current limit error. | Excess current in the modulation circuit controlled by the PCB. Check wiring and modulation current; if the EV2 valve is correct, replace/repair the PCB. |
| ALL 79 | Fault due to lower current limit EV2 SGV. | Modulation current below threshold due to output/driver fault on PCB or wiring. Check the signal from the PCB and the condition of the gas valve; if it functions, the cause is the PCB. |
| ALL 95 | Fault due to micro interruptions in the flame signal. | Unstable ionization reading due to flame entry fault on the PCB or noisy power supply. Measure ionization microamps and voltages on the PCB; if electrode/gas are OK, 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.
