  1. I have an older (2003) Sundance Altamar 880 spa, which are going into protect mode (watch dog error, four dashes). I can reset the error by turning of the power with the circuit breakers, but the error reappear after some time. As long as the water is cold, the massage pumps operate and the error stays away, but as soon as the water is warm enough for the massage pumps to stop, the error appears. The display also shows the "OH" (overheat) error briefly before going into protection mode. I have removed the cover in front of the heater, and it is very hot to touch. I don't know if this is normal? I have read about the watchdog error on these spas, and many are suggesting that the capacitors may be bad. They seem fine here. I personally suspect the circulation pump, as it is suspiciously quiet. Could a failed circulation pump cause these errors? Thanks!
  2. Hi - Frequent guest, first time asking for help. Thanks in advance and thanks for past help as a "browser"! 2006 Jacuzzi J325 owner here, bought from used spa dealer 3 years ago. Recent issue: working fine ( about 1 month past most recent water change) but came out to find the dreaded Watch Dog dashes error. Shut breaker off: upon power up, observed OH error code very briefly, temp was 102 (verified this, felt correct), red heater light comes on as though it's trying to get up to it's set temp of 104. With panel off, I'm hearing what sounds like the circ pump trying to come on, but it never does. ( This circ pump has been a bit noisy over the past year so I've been suspecting it could fail soon). If I leave it alone for several minutes, the watch dog dashes appear and the tub is locked. Rinse repeat, same events but obviously the temp is starting to drop over the last 2 days of testing. Currently low 90's ( we're in Phx, high ambient temps). So here's a detail: If I reboot as above and attempt to turn on the main pumps ( low and hi) they both work and the tub will operate with main pumps/ jets going for approx 5 min.....then watchdog kicks in and we start over. All the while, that circ pump never seems to come on in any circumstance. Steps: Tested temp sensor ( replaced this 1 year ago) Good . Have a spare. It's good as well. Tested ohm reading based on a guide found here on this site.....both switches seemed correct for the temp at the time. Tested Hi Limit switch ( ohm reading was about right for water temp at the time) Flo Switch "looks" like it's working correctly but can't be certain. Replaced this 1 year ago. Caps on control board "look" ok...not obviously bulging but I'm no expert. Fuse looks ok, but again...no expert here. So I leave it to the pros.....am I suspecting the circ pump without due cause ( just because it's been noisy and seems to be struggling) or am I missing something else? Thanks in advance!
