in THE MAIN WALL
My service tech serviced my Weil McLain 368st boiler today,he said that he had to take the lwco apart, to clean the inside wall of the lwco. It is a M/M #67 he said it had scale on the wall. It works ok now ,should it be changed, or clean it each year. Thanks tom

    Replace after 10 years old

    Clean once a year by disassembling the control, and if it is still serviceable, put back in service after cleaning.

    That's M&M's instructions on them, shortened for the Wall. Read the whole instruction sheet, they have it on line.
