I bought a wd 802 m and the 3 knobs for off/on, spin-med/hi and the heat-half/high are missing... Is there any chance that I can get these knobs replaced??? If so cost and where do I order??? These appear to be the same as the knobs on the all the Spendide 2000... http://www.splendide.com/manual_wdc1024m.pdf page 10 and 11... Thanks for any info
