PL (P01) Error - And how to solve it

🚨 Understanding the PL Error

  • PL Error = Flow Error
    The engine’s flow switch cannot detect water movement, causing a safety shutdown to prevent pump damage.

  • Not necessarily a technical issue
    A PL or P01 error can often be caused by something blocking the water flow. After refilling the Icetub with clean water,  air could be stuck in the piping. Also, dirt might have gotten stuck in the pump. This is why using the Icetub filter is so important. Could also be just a dirty filter signaling the need to replace it.

  • Annual Maintenance
    Remind yourself, whether annual maintenance was performed on the engine? Find our engine manual here:

🔧 Try the Following Steps: (While engine is OFF)

1. Inspect and Replace the Filter

A clogged filter can block water flow.
➡️ Check your filter for heavy saturation, dirt, or debris.
➡️ If dirty, replace the filter using this video guide.

Note: Make sure the filter is not installed dry. First submerge it under water to release trapped air.
Note 2: Filters should not be cleaned and re-used, it can make it harder for the pump to pull water through it and the effectiveness of the filter will wear out if it's continuously cleaned and re-used.

2. Air Release for Cooling Unit

Air trapped in the system can also cause flow issues.
Perform an air release by following this video guide.

 

3. Check the Pump Power Connection

Sometimes the pump’s power adapter can disconnect.
Open the back cover of the engine, and ensure the pump plug is securely connected.

4. Flow Sensor Troubleshooting (Specific Engine IDs)

If your engine ID is 1.089.001.2053 , a water flow sensor issue could be the cause.
Follow this Flow Switch PDF guide.

5. Ozonator Settings and Air Leaks

The Ozonator icon should only appear when the pump is running, not flicker constantly. If it's flickering hold "UP" and "DOWN" buttons for 5 seconds to return it to Automatic mode.

🛠️ If the Issue Persists After Troubleshooting

If, after all these steps, your engine still shows the PL error:

  • Confirm that after removing the filter and blowing water through the inlets with a hose for 5+ seconds, the PL error still appears.

  • Confirm that no physical obstructions (dirt or debris) entered the pump. (To remove the pump follow page 26/27 of the engine's manual in the annual maintenance section )

  • Confirm that Ozonator settings are correct. (Not flickering)

🛑 Important: Improper Filter Use Can Damage Engines

Sometimes the root cause of a persistent PL error is incorrect or missing filter use.

  • Dirt, hair, and oils can accumulate inside the system when filters are not used properly. This eventually leads to pump or flow sensor damage.

  • There are visual examples of damage caused by improper maintenance available upon request.

  • Sometimes PL error can appear due to improper winterization. Make sure the engine is disconnected and drained during -5C weather and below. Using the engine beyond that point, will cause damage to the engine, showing up with leaks and error codes.
