I inherited a 1997 Beachcomber Model 550 that is not heating but I wish it did. Here' what I know: -the motor is running normally and the pump is working fine, both are brand new -there are no error codes on the topside controller but the red heating status light does not come on -when powered up the actual temperature reading is 54F now. Was 56F yesterday which I'm assuming means the water temperature sensor is working -the temperature setting on the controller is set at 100F. I am able to raise and lower this setting but nothing changes in terms of operation -heater element resistance is 15 ohms but no 240v at terminals -the heater relay on the circuit board shows 253 ohms but is not closing which explains no 240v at heater element terminals. Manually closing the relay gives 240v at the heater element. Having trouble testing for 120v at relay, not sure how to do this. -with the power off, pressure switch is open. Not able to confirm if the pressure switch is closing when powered up, not sure how to do this either. -removing the pressure switch/high temp sensor connector (4 pin combined connector) from the circuit board before powerup causes a Sn fault -checked the high temperature sensor for continuity, not showing any resistance. I understand Ohms should vary with temperature, ie. higher when colder and my guess this is the cause of the problem. -circuit board looks ok, ie. nothing burnt, no cracks, continuity in several circuits I checked.. Any insight is appreciated not to mention some advice as to where a guy can find parts for older Beachcomber hot tubs. Thank you.
Hi! Im new to this forum, I just acquired a older model Jacuzzi hot tub. The model is 8780000 ( Caressa). Got a pretty good deal on it since it doesnt leak, and all the side wood is in great condition. Its wired for 115vac 20 amp. I ran a dedicated line (gfci of course) and bonded the tub to code. However when we plugged it in the first time we realized it wasnt heating after 24 hours it didnt warm up not even a degree. After looking up some information I realized it could be the heating element. Below is what I did to replace it Unplugged the tub drained the tub to below jet level loosened the four hose clamps removed the bond bar line from top of the manifold unscrewed the high limit housing from the manifold removed the connection to the element prongs Carefully slid out the thermister for the high level switch I noticed that the old element was welded into the manifold below is how i replaced it Used a band saw and cut the exposed prongs off the manifold Used a grinder to grind the remaining prong flush to the manifold Used a 1/4 drill bit to break the weld around the element I ordered a new element ( its a little shorter 10" vs 16" however what I read it doesnt matter Bored out the 1/4 holes to fit the 1/2 bolts for the new element Verified that the element had o-rings Tightened the nuts to the bolts ( careful not to over torque) Cleaned the Hot wire and the neutral wire from the hot tub panel with a wire brush crimped new connectors to work with the new element Moved the ground ( didnt like the ground to the manifold, bad idea so i moved it to the bond bar) Re installed the manifold and tightened the hose clamps. When I removed the old element , it was obvious to me that it needed replacement ( calcium build up, and rust was all over it, it one area it looked like it burst, maybe at some point it was hot ran? i dont know. After doing all this I was excited we were excited that we were finally going to be able to enjoy our tub ( winters coming) However it didnt ( I let the tub sit for 12 hours in the HTR/Filter mode, its only a 115 20 amp tub so i figured it would heat 1-2°F per hour but yeah it didnt) . Below are all the steps I did so far Made sure high temp switch isnt open Checked voltage to the new element ( 120v each) checked relays all seem to be working, each read positive off the ground and the magnetic coils seem to be in good shape Replaced the Filter The jets work, and the HTR/Filter button does move water around so my circulating pump works The turn dial thermostat initiates the the relays to turn the tub, and the heater on indicating light works Is there something I missed? I consider my self more than the average do it yourself kinda guy. My background is mechanical engineering so that's why I was so excited to get this older SCM tub. if anyone can help me troubleshoot please feel free! I want it to get up and running before winter. There isnt much online for troubleshooting these tubs. thanks!
I'm going to use Dr. Spa's handy-dandy "how to test your element / how power works" guide to confirm my suspicions, but I'm 95% sure my heater element is dead. I was shipped off overseas for 6 weeks and came back to relax ... in my 82 degreee tub (which was a huge disappointment). The controls appear to be heating, and as well, I never see my TED (power consumption monitoring device) say I get up to 5-8 kva like I normally do. Since I believe the element is bad, my question is whether or not any of you have a recommended replacement element? I've seen some that are titanium - does this really make a difference? The hype says that corrosive stuff won't stick to it. I'm wondering though if it heats as well?
Hi all, im new to the forum. I recently purchased a Vita Spa Vintage hot tub with a heat problem. I believe the element is bad but not to sure. After removing it I did an ohms reading and got .17 ohms. I checked Spa Depots website before I found this forum and they said most elements range from 9-12 ohms if they are good, and some can go up to 25 ohms. So far the high limit and thermostat tested good so im leaning towards the element. Its a 240v and from what the element cover says is 6000 watts. Any help would greatly be appreciated! Also is there any way to test the thermocouple? From what I can see i has 1 wire going directly to the high limit.
