| 1436452 | 2017-06-13 02:45:00 | Hey any handy electricians out there who know about electric hot water cylinders? Got woken up 4am this morning with water coming out the overflow pipe from out hot water cylinder. Ran off some hot water. Can hear the heating element kick in. Thought ok... Must have cooled the cylinder down too far. Went back to bed. Got up 1/2 hour later, had a 'weak' shower - still some turbulence in the cylinder. Ok. Went to work, and rang the wife 3 hours later, water boiling in the cylinder again!!!! Now we do have a wet back booster, but the fire is turned down overnight. So my question is,... can a faulty thermostat stay 'stuck' closed and allow the heating element to stay on permanently? I have had then going faulty and not switching the element on, but never the reverse. ???????????????????? |

| 1436455 | 2017-06-13 03:38:00 | Thanks - can confirm. Using multimeter - 240V through whole temp range. Element is only 2yrs old so should be ok. Time for a Sparky! Cheers |

| 1436456 | 2017-06-13 03:39:00 | Yeah we usually did turn the power off (until a few years ago) - might be a habit to get back into! | ManUFan (7602) | ||
| 1436457 | 2017-06-13 04:58:00 | Time for a Sparky! Get a plumber, one that does wetbacks too . |

| 1436459 | 2017-06-13 06:58:00 | Its a plumbing job and you may find they do electrical too. I know Laser Plumbing does. Do you know if its a low pressure or mains cylinder? The overflow does not generally mean it's boiling over, it could mean the pressure of the water has increased which pushes the water above the head level of the cylinder. That could be the flow regulator which is normally under the house where the cylinder is. Either way, get a plumber in and let them sort it, and if your hot water pressure isn't too great, see if they can do something about that too. |

| 1436461 | 2017-06-13 21:46:00 | Electrician here this morning. Only reason water was coming out the overflow is because the cylinder was boiling. Normally ok. | ManUFan (7602) | ||
