My Maxmatic has become fiddly to start with the Magnitop plug or Magnitube

I've bought a new Magnitop Plug or Magnitube and it will not start the Maxmatic

Your machine is most likely out of alignment

1) Re- align as per the installation instructions

There is a bad smell coming from my Maxmatic

Your Maxmatic should not cause a smell

If it does, but only occationally, try using Disposer Care cleaner available here 

If it is more persistant, then the problem is usually poor plumbing 

Waste Pipe
It is most important that a few basic rules are followed to ensure correct operation. A bad installation will result in pipe blockages, smells and a greatly reduced life expectancy of the unit and may invalidate your warranty.

  1. a) A ‘P’ or ‘S’ type trap should be used. Bottle traps must not be used.
    b) Stop ends and tee connections should be avoided.
    c) The diameter of the pipe work must not be reduced from the disposal unit to the drain. If the run to the drain is long or meandering, it is advisable to increase the diameter to 54mm (2″).
    d) A fall of 15 Degrees is ideal, it is most important that the unit drains fully.
    e) The waste outlet must not discharge over a grate.
    f) The connection of a dishwasher or washing machine outlet to the same waste will help to flush the pipe work, our units are supplied with a connection.
