My waterrower has leaking seam in the plastic tank know its not that...

Unfortunately stuff today is produce to replace, not fix and I guarantee you that Reebok does not actually produce a rower but instead just leases out it's name. So you might want to try to find out who actually makes the product, there may be some information on the machine itself.
Also, here is a link for http://www.ebay.co.uk/bhp/reebok-rowing-machine ebay search of reebok rowers, you may be able to find a second one as parts for cheap instead of buying a new display or motherboard.
You could also take the display unit to an electronics repair shop and have them troubleshoot and fix it.

You'll find the battery acid has leaked on the green cable linking the console to the buttons. I wiped down this green cable with water - removing the acid residue and the buttons started working again.

You can get to this cable by unscrewing the plastic fascia. There are six screws on the rear and two on the base of the unit.

you can buy/replace the valve, no problem, what is happening is the armature in the valve is lifting causing the water to enter the machine, if you take valve apart you should see the rubber plunger is jammed in the open position, you can trim to fit

Good News! Home Depot sells (on-line only) drawer rollers that work PERFECTLY for the Tunturi Rower machine seat rollers. The only difference is the wheels are nylon instead of rubber. Model Number R7228, Internet Number: 100142874. Item description: ROLLER, W/ 1/4" -20 STUD, 1-1/8" NYLON, BALL BEARING. There are two rollers in a package, $5 for two! http://www.homedepot.com/buy/prime-line-1-1-8-in-nylon-ball-bearing-drawer-rollers-2-pack--r-7228.html

Try to make new brackets for adapting to the screw holes on the rim ATTENTION the screws should NOT
go deeper in the rims as the original ones as they will interfeer with the internal parts and damage will result.

Sounds like the plastic liners that hold the wheel either on or together have worn out.  They make hundreds of different style wheels.  You can try going to any baby supply store that has replacement wheels that have the "same" mounting configuration and see if you can get new ones.  You might need to replace all the wheels and they may look different but at least you'll almost have a new stroller that doesn't wobble.
