M021

Balboa M021: settings were reset

M021 means the settings have been reset. The guide names this a persistent memory error and says to contact your dealer or service organization if it appears on more than one power-up. This wording is from Balboa guide 40985-G, 26 March 2014, for BP2500 and BP2600 with a TP800 or TP900 panel.

The settings have been reset (Persistent Memory Error).

Models this page covers: BP2500, BP2600, TP900, TP800

    Call if the next power-up shows it again

    The guide draws the line at more than one power-up. If M021 is there again after the next power-up, stop resetting it and contact the dealer.

When to call a technician

Call a technician now if

  • The breaker or the RCD trips when the pump is plugged in.
  • You smell burning, see melted plastic, or the water is too hot to touch.
  • The code comes back after one reset.

Also call for these, from the manual

  • Contact your dealer or service organization when M021 appears on more than one power-up. Do not open the control pack.

Questions

Did one power cut cause M021?

The guide does not say what caused the reset. It says to contact the dealer or service organization if the message appears on more than one power-up.
