  • Bosch classixx 1 minute error

    Hi all , haven't been in for while ☺️
    Anyways , got a Bosch classixx 1400 washing machine with the 1 minute error on it.
    Gets to end of cycle but then carries on with 1 minute on the clock. I've googled , all of which points to heating but results of checks below leave me puzzled
    I've also looked for a reset but my machine doesn't have a spin button which seems to be needed for reset ( mine has a dial.
    So far I've :
    1. Checked / cleaned pump
    2. Resistance checked element = 27 (fine?)
    3. Resistance checked thermostat = 06.27k , also when held number drops. (fine?)
    4. Inspected PCB visually , couldn't see any blown solder. Only signs were tiny amounts of black soot/carbon? Gave a clean with cotton bud and put back together.
    Any ideas as to the fault?
    Cheers

      Hi Dave thanx for quick response.
      1. No it doesn't heat water.

      2. No It didn't check resistance to earth ( what number am i looking for?)

      An extra bit of info it doesn't take the softener.

        well if its not heating the water that could be your problem

        there is a relay on the main board that controls the heater this may have failed or it could be a bad solder joint

            well the first thing to do is remove the board. Find the relay ( small black block normally) and look on the solder side of the board and look for any solder joint to it that does not look clean and silver
