Hi all, My machines driving me up the wall at the moment it looks like an ashbys sensei but has an inline heater in which they don't do I brought it a few years ago and am not sure who its made by. For the last 4-5  months every week i've been puting rinse through the machine due to lack of water flower, it got so bad this week that rinse didn't work so fitted a new shurflow pump looked forward to swiching it on with it being full of beans, but how wrong was i drible drible out the pump out hose again so put some more rinse in the clean tank and with in 30 second its flowing well and lasts about an hours worth of cleaning then u've guessed its time for a rinse again, i,ve tried leaving the rinse in overnight.

The machine has a filter in the solution tank the powder i use is from Craftex premium clean. Can any one recommend something stronger than rinse, or where the problem might be. I changed a pipe coming from the outlet of the inline heater the pipe in thinner than the original but I was assured this would be fine, so could it be this causing the problem or maybe the inline heater is blocked.

The trouble is the machines a bit of a nightmare to work on everythings so cramped it would take a good few hours to change the pipe again.

Any ideas would be great.

Cheers

Hi,

I live in Scotland which is the land of the pure water and doesnt ever have this prob.

Have u tried running it without the inline heater?
De-scaler is citric acid, that will blow away and carbonates built up and should be ok for a diaphragm pump.
You could fire pure white vinegar through it, properly acidic rinse. But keep the valve wand end open as it will pressurise over time (gaffa tape) Leave it for a while with the vinegar in it (say overnight) and then test with pure water (2l from asda say 20p?)

Dont know your machine, but taking bits off and inspecting them might help after all, CC machines are pretty simple engineering. It could be as simple as the pre-filter is blocked.

When u changed the pipe what did it look like in terms of its lining? Cut the old pipe in half and inspect. If you have a 2mm flow from a 20ml pipe then it might be the prob, but its more likely to be the snag points in the pressure system, ie the turns and hose coupling ends.

You might have scale problems, but you could be barking up the wrong tree.

Could be clogged up somewhere with cleaning powder residue.

Once you get it sorted, might be better using your cleaning agent as a pre spray and spray/extract just with clean water.

Cleaning agents are water soluble though, so would expect it to clear with hot water. I know some peeps have a bit of a prob with powder in the tank? Most pumps can handle slurrys, so dunno about this and most pumps have pre filters. Never had a single valve or membrane prob on a pump in 4 years with solids in the tank. Only brushes on pumps seem to go.

Maybe on higher than 120psi its a prob, but never encountered it.

From whats been said, i would say its prolly not a scale prob, as it cant build up in half an hour of use imo. More likely a leak or ropey seal thats preventing flow.

There was a post recently about filters becoming " enclosed " by a translucent material which could easily be missed at a glance.

It was simply a build up which totally blocked the filter, but was removed easily. Look closely at your filters!

 I agree Joe. In the early days I tried using powders in the tank and got all sorts of problems with flow.

If you are using an inline heater is it fair to say you are adding your powder to cold water? Try warm water. The powder disolves  better.

As someone else said, it's better to pre spray then extract using a rinse addative. A liquid one .
