My solution to this problem was to bypass the switch altogether and replace it with an inline "Square D" well pump switch. It's working great now with no issues.
Hi Jonathan.I am also having same proplem on my boat.can you please give us some more detail about your solution.(Which pump switch,how did you do.how did you bypass)
I took my switch apart and applied wd40 , put it back together and it's working for now. would like to know how to change to another switch.. Great info. Thanks
Thank you so very, very much! They did the opposite with me - installed a “dc” switch on my “ac” series 33 seaflo pump. You totally enabled me to diagnose this issue easily. I have sent the company a picture and am waiting to hear back.
Yes that happened to me with a pump only two months old. I changed the micro switch and it's running fine, but I wasn't aware of the ac/dc issue. Thank you.
Thanks Johnathan that's a great help .I no option other than to buy another switch that will fail in the future from seaflo ,will end up buying another pump non seaflo in the future
Thank you so much, I too have been fighting with the same pump and problem. I traced it to the switch but never took it completely apart the way you did , it all makes sense now. Awesome info, Thanks again
I have the A/C version, I can't get a response from SeaFlo about whether the AC and DC version of the pump uses the same pressure switch part. You just answered my question :). I've had two pumps fail over the last several years. I've looked at alternative brands but Seaflo seems to be the best despite the short life. I do use my pump every day to supply my household water (don't have a municipal water connection where I live).
Yup, I've two Seaflows and both failed. You really have to question the integrity of this company as it continues to install AC switches in DC models, while ignoring the failures. TBH, I'm just going to bring my pump closer to it's point of use and add a manual switch for now. I tell everyone who asks, to never get Seaflows. They're losing customers, but that's their karma.
A lot of these type of micro switches are actually rated for DC as well if you look in their datasheets. DC at lower currents and voltages than AC though usually. Look up your switch and see what it's rated for DC. May still be too low current for this application, or may be a bad batch of microswitches? Would be interested to know if the AC versions of this pump have the same issue?
I'm sorry... I didn't catch what the symptoms are for your failing switch. My pump behaves as if there is a leak or torn diaphragm, second pump in a year doing the same thing... first one acted up after 9 months, second one after only 3 months. I don't want to rip the pump apart without a solid idea.
Same problem here. They sent me a new pump and i got the same problem again. But many customers seem to be happy on amazon. Could it be that only some pumps have the wrong switch?
No. I think the customers that are happy are either fake or they don't use it very often. It's impossible to get a DC switch that will handle that current to fit that small of a package.
I’ve got the same problem. Did you manage to find a suitable replacement for the microswitch? I’ve found plenty of similar looking ones but not sure what I need in order to prevent it happening again.
I've had a look for 10 or 16a dc micro switches and it doesn't look like they exist. I'm guessing the housing is not big enough to accommodate a large enough contact surface or spark arrest chamber. Or there is so little demand that it's not worth mass production. Post a link if anyone finds a suitable dc replacement.
Hey! Thank you for the video!! Do you know will that works if I replace this micro switch to this one from Amazon? Funmit WB24X829 Microwave Door Switch for GE Kenmore SZM-V16-FD-63
