A kitchenware washing assembly in one embodiment generally includes a tank having an inside for holding fluid for washing kitchenware, and a heater for heating fluid within the inside of the tank. At least one securing device releasably secures the heater within the tank. The securing device has a releasing portion located within the tank that allows the securing device to be released solely from within the tank. In this embodiment, the heater can thus be removed from and/or installed within the tank without having to crawl under the tank.

What is claimed is: 1. A kitchenware washing assembly comprising: a tank having an inside for holding fluid for washing kitchenware; a heater for heating fluid, the heater including a base and a heating element coupled to the base; a chamber positioned at least partially on a side wall portion of the tank and generally defining an opening at least partially in the side wall portion of the tank such that the chamber is in fluid communication with the tank through said opening; a cover disposed at least partially over said opening; a fitting coupled to a wall portion of the chamber, the fitting having a shoulder disposed within the chamber; and at least one clamp configured to releasably couple at least a portion of the base of the heater and at least a portion of the shoulder of the fitting together to releasably secure the heater to the fitting within the chamber; wherein the at least one clamp includes a releasing portion located within the chamber that allows the at least one clamp to be released solely from within the chamber. 2. The assembly of claim 1, wherein no tools are required to disengage the at least one clamp. 3. The assembly of claim 2, wherein the at least one clamp comprises a hinged clamp. 4. The assembly of claim 1, wherein the heater includes a temperature sensor. 5. The assembly of claim 1, further comprising a control system electrically connected to the heater, and wherein the heater includes wiring that extends from the base and through an opening extending through the fitting for electrically connecting the heater to the control system outside the tank. 6. The assembly of claim 1, wherein the chamber comprises an intake chamber for receiving fluid from the tank, and wherein the cover includes at least one removable intake cover. 7. The assembly of claim 1, wherein the cover includes at least one or more openings for communicating fluid between the tank and the chamber. 8. The assembly of claim 1, wherein the chamber is formed unitarily with said side wall portion of the tank. 9. A method for installing a heater in a chamber of a kitchenware washing assembly using at least one clamp, the heater including a base and a heating element coupled to the base, the kitchenware washing assembly including a tank having an inside for holding fluid for washing kitchenware and a fitting coupled to a wall portion of the chamber and having a shoulder disposed within the chamber, the chamber being positioned at least partially on a side wall portion of the tank and defining an opening at least partially in the side wall portion of the tank such that the chamber is in fluid communication with the tank through said opening during operation of the kitchenware washing assembly, the method comprising releasably coupling at least a portion of the base of the heater and at least a portion of the shoulder of the fitting together with the at least one clamp, thereby securing the heater to the fitting within the chamber from a location solely within the chamber. 10. The method of claim 9, wherein the at least one clamp includes a releasing portion located within the chamber. 11. The method of claim 9, wherein the at least one clamp includes a hinged clamp. 12. The method of claim 9, wherein the heater is releasably coupled within the chamber without using a tool. 13. The method of claim 9, wherein the heater includes wiring, and wherein the method includes running the wiring through an opening extending through the fitting and electrically connecting the wiring to a control system outside the tank. 14. The method of claim 9, wherein the chamber includes an intake chamber for receiving fluid from the tank, the assembly including a removable intake cover separating the intake chamber from the tank, and wherein the method includes removably attaching the intake cover to the tank after placing the heater within the intake chamber. 15. The method of claim 9, wherein the method includes removably plugging the heater into a connector adjacent the tank. 16. A kitchenware washing assembly comprising: a tank having an inside for holding fluid for washing kitchenware; a chamber disposed on a side wall portion of the tank and in fluid communication with the tank; a pump for providing a fluid flow along a flow path through the chamber between the tank and the pump; a heater for heating fluid during operation of the washing assembly, the heater including a base and a heating element coupled to the base; a fitting coupled to a wall portion of the chamber, the fitting having a shoulder disposed within the chamber; and at least one clamp configured to couple at least a portion of the base of the heater and at least a portion of the shoulder of the fitting together for releasably securing the heater at least partially to the fitting within the chamber and at least partially within the flow path between the tank and the pump, the at least one clamp having a releasing portion located within the chamber that allows the at least one clamp to be released solely from within the chamber; wherein at least one of the base of the heater and the shoulder of the fitting includes a tapered portion that cooperates with the at least one clamp to pull the base of the heater and the shoulder of the fitting together when the heater is secured to the fitting within the chamber by the at least one clamp. 17. The assembly of claim 16, wherein the at least one clamp comprises a hinged clamp. 18. The assembly of claim 17, wherein the hinged clamp further comprises at least one end portion configured for releasably receiving the releasing portion and securing the heater within the chamber. 19. The assembly of claim 16, wherein the side wall portion includes an opening, and wherein the chamber is an intake chamber positioned on the side wall portion generally at said opening such that the chamber is in fluid communication with the tank through said opening. 20. The assembly of claim 19, further comprising a cover configured to be disposed at least partially over said opening, wherein the cover includes at least one or more openings for communicating fluid between the tank an the chamber. 21. The assembly of claim 20, wherein the flow path of the fluid in the assembly circulates from the tank, through the at least one or more openings of the cover, past the heater, to the pump, and into the tank. 22. The assembly of claim 16, further comprising a sealing member disposed between the base of the heater and the shoulder of the fitting when the heater is secured to the fitting within the chamber by the at least one clamp. 23. The assembly of claim 16, further comprising a temperature sensor coupled to the base of the heater. 24. The assembly of claim 16, wherein the at least one clamp includes a tapered portion configured to bias the base of the heater and the shoulder of the fitting together when the at least one clamp couples the base of the heater and the shoulder of the fitting together. 25. The assembly of claim 16, wherein the base of the heater and the shoulder of the fitting each define a generally circular shape, and wherein the at least one clamp includes two semi-circular members configured to contact the base of the heater and the shoulder of the fitting when the at least one clamp couples the base of the heater and the shoulder of the fitting together.
