Intermittent fault with front washers

[Fords4me]

Hi everyone.  This relates to a 2014 Mk III Focus.  The washer jets work fine in pre ignition mode, so it would seem that there are no blockages or a faulty pump.  However, when the engine is started, there is just a dribble of water which comes out.  Local Ford dealer is saying if it’s not the water pump, the car will need a whole new main circuit board costing 100’s of pounds.  Any suggestions for a cheaper fix?  Thanks.

There is a problem with this year of focus where the pump leaks and tracks down the wiring into the bcm. Check for any corrosion on the plugs.

Thanks for the suggestion.  I will take a look at the plugs and see if there is any sign of corrosion.
