leak at heater element

The tub perforations at the heater leaked and water dripped onto the fastening nuts and the electrical connections. I ordered a new heater element and it did not have the necessary nuts to fasten it to the tub. I had to go back and order them separately. The original nuts are very unique and cannot be substituted for.The manufacturer should send them with every heater element because this leaking problem is very prevalent on these machines.
