Is your OASE Filtoclear fish pond filter shorting out your electricity? Remove the 4 screws holding the UV light into the filter to check if water has gotten into the electrics of your Filtoclear.
If your electrics are water damaged, often there is no need to replace the whole filter. Simply replace the electrics.
Also check to make sure that the quartz sleeve has no cracks in it and that the O-ring is still good. Give us a call if you have any problems, or are unsure what to do.
Let us throw in a free 11 watt globe to keep you going. :)
