The best way to free the clog from the valve is to remove the base to get access to the valve and push a 1/16" drill inside to clean out the contamination. We do not recommend disassembling the top or bottom end of the valve liner, as it may be very hard to re-assemble once apart
Tools needed:
Flat blade screwdriver
Phillips screwdriver
1/4" nut driver
1) Remove the valve rod with a flat blade screwdriver
2) Flip the melter over with the base facing you and remove the qty. 2 Phillips Screws and qty. 4 # 8 Screws with a 1/4" nut driver
3) Run a 1/16" drill or smaller or an unfolded paperclip into the valve to free the contamination/clog.
