Welcome to our forum.
There is at least one more. My Excalibur 4000 is just over 5 years old, so now I'm on my own. I'm really surprised Dynasty couldn't hire someone in the Chicago area to help you, though you would have paid a trip charge. My dealer went out of business a few years ago and it was an ugly situation with finger pointing, but the courts decided against my dealer. I had a pump go bad and Dynasty contracted with the local Master (at the time ) dealer to fix it. Then as you did, I had a diverter go bad (probably from people turning it with the pumps on high, which your not supposed to do, but I've never found it in the manual. That time Dynasty contracted another guy to fix it, which he did. Each time costing me $75-100. But Dynasty did honor the parts warranty. As you may have seen in the other thread, I have just purchased my 3rd cover in 5 years, this one I hope will outlast the tub. My tub is definitely a therapy, low bells and whistles model.
