There is some rhythmic clicking that is coming from my pool pump - its only 2 years old. To me it sounds like it is coming from the fan at the motor end, like maybe the fan blades are hitting the housing or something is stuck in the blades. I don't think it is the impeller - I'm not having any telltale flow or pressure issues, simply noise. I tried to remove the screws to get the shroud/cover off, but I was starting to strip the first screw since it's so tight and then I realized that there's a screw underneath that's too close to the equipment pad for me to access without lifting out the whole motor anyway. Ugh. So all this to ask a really dumb question - in case there is simply debris that has gotten into the fan, would there be any harm to spraying inside with a garden hose to see if I can dislodge it or would I risk ruining the motor and/or other electronics? Trying to avoid an expensive service call over something trivial.
