LGR Extreme constant E4 errors, 11 months old

Back to List

I've looked through the posts here and have seen to check drain line for obstructions (none, I can easily blow it out), run the purge manually (blows bubbles mostly, some water but not nearly the solid stream it used to be), disassembled the unit to check the electric connections (sprayed with some electrical cleaner/deoxidizer), and pulled the pump to clean the holding area and "lid" with a mild cleaner and microfiber towel.  Did that at 10 months from new, and have repeated the process 4 more times in the following week.  Seems to run a little better for the first 12~14 hours, then runs worse for ~24 hours (pump is much louder)  before stopping completely sometime after that.  

Have I missed anything?  What's next?

Dear Brian,  

Thank you for reaching out and providing detailed information about the issue with your LGR Extreme unit. Based on your description—frequent E4 errors, irregular water flow during manual purging, and increased pump noise—it appears that the pump may be malfunctioning. 

Since your unit is still under warranty (11 months old), we recommend contacting our Technical Support Team for further diagnosis and repair. Rest assured, we'll ensure your device is functioning properly.
