A technician confirms the cause on site rather than guessing from symptoms.

Most Del Mar repairs for this run $250 to $1,600, depending on which part has failed. See the Del Mar cost breakdown for the local band, or call for a free written quote.

You can safely run the first checks: confirm the pump is running and flow is strong, and check the thermostat is set above current water temperature. Anything involving wiring, gas, or a submerged fixture should go to a licensed Del Mar pro.
Does Del Mar water affect this?
Del Mar water is rated moderate at 10-12 gpg, so scale is less of a driver here than coastal air and normal wear.
