I no this is a silly question but i will ask it. Are you using Pure Water? dont want to offend you but i have seen and spoke to people whom use normal tap water and did not no they needed pure water, and wounded why they lost alot of customers.

If you are using Pure Water then prehaps you are not useing the pole correctly ie in rinsing. Nearly all problems related to WFP issues are user error and not the system. This might help http://www.squeakyclean4u.com/wfp/wfp.PDF

You can clean windows with a TDS reading of 035 but it becomes harder to clean with this level. I tend to stay within the region of 000-009 TDS reading to clean windows with.

If your in a hard water area then DI resin will deplet very fast indeed.
