What the LPIn error code actually means

Your oven's internal steam boiler has two sensors that monitor water level, and they are giving conflicting readings. This is often caused by mineral buildup or limescale inside the boiler interfering with the sensors. Running a descaling cycle is the recommended first step to try to resolve the issue.

Questions people ask about LPIn

What does LPIn mean on a Electrolux oven?
LPIn indicates a conflict between the two boiler water level sensors. Specifically, the working probe is reading as active while the safety probe is reading as inactive, which is a condition the control system flags as a fault. The most common cause is humid lime deposits inside the boiler shorting or interfering with the sensor contacts. Running a descale cycle with C25 tablets is the recommended first diagnostic step.
Is it safe to keep using my Electrolux oven when LPIn is displayed?
Continuing to operate the steam functions of the oven while LPIn is active is not recommended. The safety probe is reading as off, which means the boiler's secondary level protection is not functioning as intended. Using the appliance in this state could allow the boiler to operate outside its safe water level range. Address the fault before resuming steam cooking.
Will resetting my Electrolux oven clear the LPIn error code?
A simple power reset is unlikely to permanently clear the LPIn error if the underlying cause, such as lime buildup or a sensor fault, has not been addressed. The code will typically return once the oven resumes normal operation and the boiler sensors are polled again. Performing the descale cycle and inspecting the X25 connector are the correct steps to resolve the fault rather than relying on a reset.
Can I fix the LPIn error myself without calling a technician?
In many cases, running a complete cleaning program that includes a rinse and descale cycle using two C25 tablets will resolve the fault if lime buildup is the cause. If the error persists after descaling, further diagnosis involving the X25 connector on the ACU and physical inspection of the boiler level probes is required. That level of diagnosis is more suited to a qualified appliance technician, particularly because it involves inspecting internal wiring and control board connections.
How much does it typically cost to repair the LPIn error on an Electrolux oven?
If the issue is resolved by a descale cycle, the cost is limited to the price of C25 descaling tablets, which are inexpensive. If sensor probes need replacement, parts and labor costs can range from roughly 100 to 300 dollars depending on your location and service provider. An ACU control board replacement, if required, would fall on the higher end of repair costs and could range from 200 to 500 dollars or more including labor.
