powersltc Posted December 26, 2021 Share Posted December 26, 2021 Ron P. 2004 Monaco Executive Hello. Picked up my RV from the shop on Thursday after having a refrigerator installed. I had it dewinterized. Today, I am prepping for a trip to leave in the morning. I cannot get water to flow. Fresh water tank is full. The green light comes on for the water but the water pump is not cycling or pumping. Any ideas/suggestions would be appreciated. Thanks Ron P. 2004 Monaco Executive Link to comment Share on other sites More sharing options...
DavidL Posted December 26, 2021 Share Posted December 26, 2021 So, the light for the pump is on but you do not hear the pump running? Next would be to check the fuse for the pump. If that's good, check with a voltmeter that you have power and ground to the pump. If that's good, give the pump a rap with a chunk of wood...possibly the bearings are semi-seized. If it runs then, or doesn't run then, time for a pump or pump rebuild. Link to comment Share on other sites More sharing options...
Jim McGarvie Posted December 26, 2021 Share Posted December 26, 2021 Since this happened immediately after dewinterizing, I would suspect whatever procedure is prescribed for your coach was not followed completely. Link to comment Share on other sites More sharing options...

Dr4Film Posted December 26, 2021 Share Posted December 26, 2021 You should also check the Intellitec Water Pump 10 Amp Latching Relay to make sure that it is working. If you are getting 12 VDC to the motor than it is most likely the motor and not the relay. Although there are fuses in the water pump bay plus another relay that actually sends the 12 VDC amps to the motor. Any one of those could be the culprit. Second photo shows the fuses, latching controller relay and in the very lower right-hand corner you can just see the corner of the high amp relay. This is all mounted on my water pump bay wall. There is also an inline fuse just before the motor itself. You have to get your DVOM and start tracing the power to see where it stops. 1 Link to comment Share on other sites More sharing options...
Gary 05 AMB DST Posted December 27, 2021 Share Posted December 27, 2021 Ron, is the water pump running? You said it is not cycling or pumping. Has the pump lost its prime? Gary 05 AMB DST Link to comment Share on other sites More sharing options...

kenandjoanne2002 Posted December 27, 2021 Share Posted December 27, 2021 Ron. I have had that problem several times. The two wires going into the pump need to be wiggled and maybe a shot of electric contact cleaner. Often this just takes a couple of seconds. My original pump the cheap male electric connections just corroded off. Replaced the pump but kept the old one and wired it direct. Link to comment Share on other sites More sharing options...
georgecederholm Posted December 27, 2021 Share Posted December 27, 2021 Ron P, On our 2005 Exec, there are a couple of in-line quarter-turn ball valves right near the water pump. Is it possible that during dewinterization or installation of the refrigerator ice maker line someone turned off one of those valves and forgot to open it? Another thought is did someone turn off the Maniblok valves? One simple way to verify the pump is powered and operational is to slightly loosen the fitting on the pump output side. If water flows, the pump works. 1 Link to comment Share on other sites More sharing options...

Gary 05 AMB DST Posted December 28, 2021 Share Posted December 28, 2021 Ron, what was the solution? Gary 05AMB DST Link to comment Share on other sites More sharing options...
powersltc Posted December 28, 2021 Author Share Posted December 28, 2021 Ron P. 2004 Monaco Executive Simple solution, but if you don't know, you don't know. The negative connections were not connected. Why the shop separated them, I don't know. Thanks. Link to comment Share on other sites More sharing options...

Since it just came out of the shop for dewinterization I suspected it was something they did. I'm not a big believer in coincidences.... Link to comment Share on other sites More sharing options...
Frank Bergamo Posted December 28, 2021 Share Posted December 28, 2021 Maybe the shop needs work? Just saying. Never know now days. Link to comment Share on other sites More sharing options...
