Today my MC250 started putting red crystals into my system and making the water a rusty colour, i had to isolate it and clear all filters in taps, washing machine, showers and it has blocked my saniflo. Has anyone had this problem?

I've been having problems with our MC250. So far I've found a lot of complaints on:
One of these suggests a replacement head is the best bet and points you to:
I'm going to give it a go as I've had my original head off the machine today.

MC250 Not so much an answer but a question to ask MNH and Stephen say you have them in pieces -do you still have the manual on how to set up the time clock etc?
My house is leased out (while I am abroad) and the previous tenant has taken or lost the instructions therefore neither myself or new tenant know how to operate/reset it. If anyone has the instructions please post response. Thanks EPS

Hi Guys,

I have mine in pieces also. It was leaking from around the top of the unit where it goes into the main tank.

The plastic type jubile clip has broken and all the seal are covered in scale.

I am trying to get a replacment clip and seals but a parts list would be handy.

Thanks in advance for any help.

I have been looking into this problem and it seems that it is very common. This seems to be due to the fact that none of the printed circuit boards in the controls are protected sufficiently from the salt and there is a common seal failure which then allows brine onto one of the sensors. There seems little point in repairs as they don't last for long. I have discovered that there is a replacement head which fits to the resin tank which is much more reliable. I will post again when I have found a supplier for this.
