Descaling a Rocket Giotto.

havent had a chance yet... was going to try it this weekend just to see if I can overfill...
Already did a standard descale soak last weekend without overfill and have noticed better steaming than before... so probably would do a full descale again in December...
but at the mean time, will try to figure out this problem first...
Will update if I can get it to work... hopefully with video too

Hey Okitoki,
How'd you go with the descale?? Any further attempts?

It's possible that it touched the side cover and is getting earthed. I will try again by wrapping it up in sticky tape first to isolate it before turning it on.

Yep that's the water level probe...hmmm...my only thought is that you might be earthing it somehow. Sorry I can't give any further advice. Can't say I've had that problem myself.

Are you sure you disconnected the water level probe and not the safety valve? I'm no expert on the Giotto, but once you disconnect the water level cable and switch it on the pump should kick in.

Can't remember who originally wrote it or where I got it from but here is my version of the instructions.
Disclaimer;
I am not an expert.
I'm sure there are different methods to successfully descale a machine.
This is just a method that has worked for me.
Follow the instructions at your own risk.
If in doubt, seek the advise of a professional.
Descalling procedure;
* Switch to tank mode if you've got the rotary pump model in a "plumbed in" configuration and ensure water is being drawn from the tank
* Turn off machine
* Open hot water tap to empty out tank
* Tilt machine onto its right side (looking from front), open hot water tap to get all the water out of the boiler
* Stand the machine up again
* Disolve the appropriate ratio of water/descale solution and put that into the tank.
* Turn on the machine, boiler will fill with the water/descale solution.
* After it comes up to pressure open the hot water tap to get the solution coming out of the tap
* Run the Brew head
* Once your’e happy that the solution has been circulated through, leave the machine sit (switched on) for 45-60 mins.
* Make up another batch of water/descale solution and put it in the tank
* Again circulate more solution through the machine by opening the hot water tap and brew head. You should notice a blue/green tinge in the water
* Let sit for another 45-60 mins (switched on)
* Open the hot water tap to empty the tank
* Turn off machine
* Tilt the machine on its side to empty the boiler
* Fill with fresh water
* Circulate the fresh water through the hot water tap and brewhead
* Probably needs 3 to 4 fresh water tanks of fresh water to flush out the solution.
* If in doubt, taste the water after it cools a bit

I would strongly advise against holding any wires in your hand whilst the machine is live unless you know exactly what your'e doing.
I've got an easy step by step guide somewhere that does not involve dismantling. I'll post it once I find it.

oh i see.... i had thought of that when I left the wire off on the side of the machine and it may have touched the side panel... so I held the wire in my hand and it still didnt work...
However, based on what you have said... I interpreted it as I should have left the machine ON when I unplugged the water probe wire to trick it to overfill? I thought it was advised to turn machine off when pulling wires?

No, just unplug the wire, that then unearths the circuit in the same way the circuit is unearthed when the wire sensor in the boiler isn't touching water.
Did you perhaps take the wire itself out, such that you somehow earthed it by touching it off something else?

Yes I have turned on the machine after filling up with descale water and unplugged the water probe wire.
I guess I assumed the water would refill without the sensor attached.
Do I take the whole probe out instead?

Sorry to ask a dumb question, but did you both turn your machine back on after disconnecting the sensor and reconnect water?Originally posted by okitoki View PostHey all. After doing some reading on how to descale aHX machine. I thought I would tackle my giotto today
I first taken off the top cover, heat up machine to 1.3 bar. Turned it off and turned on the water tap and drain off about 1 ltr of boiler water to be fill in with descale solution.
Now, I removed the water sensor probe connection (single clip wire) thinking that this should make the pump turn on and start filling up manually.
But it doesn't start the pump at all. I have both the hot water and steam knob s in the open position.
If I reconnect the water sensor (when turned off) and start the machine again, it would start pumping water again to fill up the boiler.
Am I missing somethig if I want to overfill the boiler for descale?
Thanks

A simpler way to do it, without removing the probe, is to tilt the machine at 45 degrees each side. This initiates the pump and overfills the boiler.
