internal leaks on bosch dishwasher

New to the site and in desperate need of how to fix my bosch dishwasher.

Welcome to the site. Can you be more specific with what your problem is. Model of dishwasher, exactly what has gone wrong where in the washing cycle it happens. A few photos also can help.

Probably best to disconnect it, pull it out of its housing and lay it on its side on a large sheet......expect some water around whatever you do.
Hopefully it will just be a rubber hose from the pump to drain hose, or similar.

Bosch model sgs45c02 check water light came on. Programme timer would show that it hadn't finished its cycle but everything seemed clean and no water left in bottom. Tilted machine in every direction and sure enough there was water in the bottom. Managed two more washes after that but now light is back on and the pump keeps going even though there's no water in the bottom of drum. Did the tilt thingy again and took both sides off and the back and put the machine on. Water sprays out at the back and the right hand side from what could be seals or maybe small pipes at certain points of the cycle. There does appear also to be a blockage on the left side of the machine in the moulded plastic in the top right hand corner. I didn't notice this until after the programme had finished. It looks like it is just a void and wouldn't affect anything but I will set it going again soon and watch that bit.

Either I have stumped everyone or I have not entered the details correctly on the site. Not received any advice that I know of!!

The water collecting in the bottom will activate a float switch that causes the program to stop.
From your description, you have found the cause of the leak. The "moulded plastic" on the left should be cleaned out if you can. I believe that you could probably buy a replacement on-line if you search for spare parts for your model. Check out the pipes that are leaking to try and determine if they just need cleaning or if they have split and need replacing. They theoretically might be designed to leak if the pressure is too high within them to prevent damaging something else.
