hi

anybody got any ideas as to why every time my machine a(baumatic mega 6ss) goes onto rinse it sends my plumbing into overflow mode from the tank in the loft, having just moved surely both plumbing systems cannot be at fault as it happened at the old house aswell even after having the ballcocks replaced

Solution Summary

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Baumatic Mega 6SS linked to loft tank overflow when connected to hot supply

The problem
A Baumatic Mega 6SS caused water to overflow from the loft tank, reported mainly when the machine went into rinse. The issue had occurred in two different houses, so the original poster doubted it was simply a plumbing fault at one property.
Likely cause
The strongest supported explanation was that the machine may have been connected with the hot and cold supplies the wrong way round, or the supplies themselves were misidentified. This would fit the later report that turning off the hot supply stopped the overflow, despite rinses normally using cold water. An earlier suggestion was that the machine itself could not directly make the loft tank overflow unless it was only triggering an existing plumbing issue.
What fixed it
Recommended action was to check whether the hot and cold inlet hoses/taps were connected correctly, and confirm whether the machine was actually taking hot water during the rinse stage. No repair to the appliance itself was confirmed in the discussion.
Checks to try
  • Observed that turning off the hot water supply to the machine stopped the loft overflow
  • Check whether the hot and cold hoses/taps are connected the correct way round
  • Check whether the machine is taking hot water during rinses

Hello Joanne

If you really mean the water overflows through the overflow pipe in the loft then I can't imagine any way a washing machine could cause that. It could trigger something if the plumbing is already dodgy by simply demanding cold water for rinsing, but your washing machine can't possibly cause the tank in the loft to overflow, especially as you say - in two different houses. If by any chance you mean the tank starts filling all the time it could be that the washing machine is siphoning - Washing machine constantly fills with water and goes down the drain

hi,for some reason the overflow only happens when the hot water is connected my husband turnt the supply to the machine off and presto no overflow from the roof and by coincedence the people that moved in our old house have exactly the same machine but no overflow my husband discovered when he collected some mail and chatted to the new owners all very strange

Bizarre, especially as you said it only does it when it goes into rinses, which has nothing to do with the hot water. Make sure you haven't got the hot and cold hoses the wrong way round on the washing machine. Don't take any notice of the colour of the taps or hoses as people can install them wrong. Check that when it's taking water on rinses, that the water isn't hot. If the machine is rinsing in hot water it will crease all the clothes and drain all the hot water from the tank everytime you wash.
