If you find that the WASH LED is coming on more frequently than the
established schedule on the wash reminder schedule, you may have a
buildup of residue on the ionizer wires. If the collector plates on the
cell(s) look clean, you can try wiping the ionizer wires with a clean cloth
instead of washing the entire cell.
You might also consider whether some activity in your home has
changed, causing the cell(s) to become dirty faster. Have the windows
been open more often? Has someone been smoking more often? Has
someone taken up woodworking or some other hobby that creates
dust?
NOTE: You may let the heating or air conditioning system operate
normally while the cell(s) are being washed. Simply turn off the air
cleaner switch.
The prefilter(s) should be vacuumed, brushed,
sprayed with a garden hose, or washed at the
same time as the electronic cell(s).
