Hi, had exactly the same issue, water pump stopped and couldnt open the boot, found fuse 8 had blown, used the fuse in number 7 which is a 20amp to check, boot opened and washer started, put the fuse back in and the central locking wasnt working, disconnected the battery as per above, reconneced 10 minutes later which reset the central locking. hard to under stand why they would put the boot and the washer on the same fuse. Worked for me. Adrian
