I have just had a reply back and here it is
Yes I am aware of this issue on some types of Foot Controllers, in most cases it can be rectified with an Internal adjustment in the Foot Controller.
If you are in the area of Janome Seven Hills please call in and we will assist, if not convenient please call at you nearest Janome Dealer ( addresses found on www.janome.com.au )
( Unfortunately there is no Customer service procedure for this as there is an Electrical safety issue so it must be inspected by a Authorised Technician )
If you choose Hobbysew Top Ryde you will need to ask them all those questions as every Dealership has different repair processes.
Please call them and ask their costs etc.
Most new foot controls cost $ 89.00 - $109.00 depending on the type, so please ask the store what they charge, before you go ahead.
We can check it here for you free of charge, if it needs adjustment then a reasonable fee ( $25.00 -$40 ) may apply but you will need to bring your machine also.
So that is the response. I live quite a drive - over an hour from Seven Hills on a good day without traffic so will have a think about this. I am very happy with the machine it does everything that I need and more and I have lived without the pedal for several years so I guess I will continue on doing so. I will be at the Top Ryde store tomorrow and will call in to ask the relevant questions.
