What it is
The MAGNETIC UNIT is a Worcester Bosch spare part for the manufacturer's domestic heating appliances. It sits in the appliance water circuit, where the magnetic element collects magnetite and other ferrous debris carried in the system water so that it is held rather than left to circulate. It is supplied under Worcester Bosch part number 87085013090.
Signs this part needs replacing
- Black magnetite build-up returns quickly after the unit is cleaned.
- Black debris continues to circulate in the system water even with the unit fitted.
- Cold spots, reduced heat output or noisy operation traced to sludge in the heat exchanger or pump.
