I was wondering I have 432 hours on my truckmount. The water line is all clogged with soapy residue. I don't know if it is from the rinse solution or not. How is the proper way to descale this.
Good tip about turning the heat up. I found that out the hard way last year. I also found that it's a good idea to mix the descaler up in a bucket 1st then dump it into your water box. This eliminates the possibility of dumping to much in at once and clogging up your water box with powder.It very likely is from the detergent you're using. Some detergents are not meant to be used in high heat truck mounts. Found that out the hard way. If it is your detergent it will look white and chalky and can accumulate in areas like the quick connect coming out of the machine, the solution lines, and in your jets and quick connects on whatever tool you're using at the time. Once I even had it solidify in the handle of my Hydroforce completely blocking it off. If I do use a detergent I make sure it's formulated for use in truck mounts or I use an acid rinse or soft water rinse only. That has eliminated all the above problems for many years now. Also, if you're not using a water softener you need to get one because that will greatly help hard water scale from building up.
If you've got a lot of build up I'd get a TM descaler. I put one full quart of Matrix Descaler in my water box. I turn my temp dial up to prevent losing it through the solenoid on the waste tank, but leave any diverter off. You don't want the machine getting too hot. You can recirculate for 15 or 20 minutes back to the water box, then hook up your solution hose and your tool and just run enough through and shut if off. Let it sit a while and flush it all out with fresh water. If you have a lot of build up in the lines it may take a while to get it all out. Sometimes I just use a whole gallon of vinegar to flush my machine out. I rarely have to descale with a water softener. I suggest either cutting the amount of detergent you're using in 1/2 or ceasing using it if you think that caused this problem. I also suggest NOT buying carpet cleaning detergents local.
1/2 hour is too long to be running descaler. You can easily melt the seals inside the pump at that time frame. Descaler shouldn't run past 15 minutes. 20 minutes is even stretching it.What emulsifier a u using? That could be your problem..At the end of the day and every day shut off your chemical meter off and flush/ flush till it runs clear.I rarely have to descale and should be done around 500 hrs. Add the de=scale to your water box for around 1/2 hr. Then flush/flush Follow the directions on your de-scale bottle
