Depends what's wrong with it. If it's just broken the connection between the fascia and module, then a careful superglue job would be relatively inexpensive. Check by removing the lid WITH POWER OFF and checking whether the green plastic shaft from the PCB is damaged or not. Turn carefully with a pair of long nosed pliers if you're not sure.
If the timer has gone,, or if the green shaft is too badly damaged to patch together, you'll need a new module. These are the best part of £200, or someone in the trade to get you a reconditioned one, which will cost about £50.
Apart from anything else, it certainly proves the rule that most expensive repairs are caused by the user trying to continue using the machine when the bearings are shot/timer is sticking etc.
