Installation, Operation and Care of LXe SERIES DISHWASHERS SAVE THESE INSTRUCTIONS GENERAL The LXe Series dishwashers are fully automatic, front-loading dishwashing machines. The LXe series machines are capable of doing 24 to 34 racks per hour, depending on model. All LXe Series dishwashers shut down automatically 4 hours after last use to conserve energy. All LXeH and LXeR dishwashers include Sense-A-Temp™ to insure proper hot water temperature during rinse.
INSTALLATION UNPACKING Immediately after unpacking the dishwasher, check for possible shipping damage. If this machine is found to be damaged, save packaging material and contact the carrier within 15 days of delivery. LOCATION Prior to installation, verify that the electrical supply agrees with the specifications on the machine data plate, which is located on the top of the door. Steam generated from normal operation may escape from the door. Wood, laminates, veneers, etc.
A water hammer arrestor (meeting ASSE-1010 Standard or equivalent) should be installed (supplied by others) in the common water supply line at the service connection. The plumber connecting this machine is responsible for making certain that water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher.
ELECTRICAL CONNECTION Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes. Disconnect the electrical power to the machine and follow lockout/tagout procedures. ELECTRICAL DATA Complied in accordance with the National Electrical Code NFPA-70, latest addition. For supply connections, use copper wire only rated at 90°C minimum.
Connection Method 1. Remove the lower front panel by removing the two screws at the bottom of the panel (Fig. 1). REMOVE TWO SCREWS Fig. 1 2. Open door of dishwasher and remove the two left screws and the top right screw (Fig. 2). Pull top of unit forward approximately 1” and remove the left side panel. REMOVE THREE SCREWS Fig.
3. A hole for 1” trade size conduit is supplied at the lower right in the back of the machine (Fig. 3). If necessary due to space requirements, remove the knockout and use a 45° fitting. KNOCKOUT Fig. 3 4. Install 1” trade size conduit and fitting. Leave at least four feet of electrical line between wall connection and machine. This allows machine to be pulled away from the wall for cleaning and/ or servicing. 5. Feed wires thru base of unit to front of unit.
CHEMICAL SANITIZER (LXeC & LXePR) Items such as pewter, aluminum and silver will be attacked by sodium hypochlorite (bleach). Therefore, chemical-sanitizing dishwashers should not be used to wash such items. On models LXeC & LXePR, the chemical sanitizer pump is factory-set for use with 6% sodium hypochlorite solution. If 8.40% sodium hypochlorite solution is to be used, contact your local Hobart Service Office. On LXeC models, place a 1-gallon bottle of 6% or 8.
PRIMING CHEMICAL PUMPS When a chemical becomes empty, the priming operation starts automatically the next time the machine is turned on or a wash cycle is started. Note that the initial prime time for all pumps (Detergent, Rinse Agent, and Sanitizer) is 60 seconds. If the chemical is not sensed within 60 seconds, the add chemical indicator will flash.
CONNECTION INFORMATION (AFF = ABOVE FINISHED FLOOR) Do not premix other chemcals and sodium hypochlorite (liquid bleach). Mixing may cause hazardous gas to form. LEGEND Required flowing water pressure to the dishmachine is 15-65 PSIG. If pressures higher than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the dishmachine (by others). E1 ELECTRICAL CONNECTION: 1-3/8" DIA. HOLE FOR 1" TRADE SIZE CONDUIT; 4-5/8" AFF.

OPERATION Items such as pewter, aluminum and silver will be attacked by sodium hypochlorite (bleach). Therefore, chemical-sanitizing dishwashers should not be used to wash such items. If your dishwasher is a chemical-sanitizing model, frequently check the sanitizer bottle to make sure there is a sufficient chemical supply. BEFORE FIRST USE This machine must be cleaned after installation and before being put into operation. (See Cleaning.) CONTROLS LXeC and LXeH Fig. 5 LXePR and LXeR Fig.

Dishes must be scraped and/or rinsed to remove food particles and other debris. Never use steel wool on ware to be loaded into the dishwasher. Place dishes in a rack. Do not stack dishes on top of each other as water must have free access to all sides of every dish. Stand plates edgewise in a peg-type rack (Fig. 9). Cups, glasses and bowls should lay upside down in an open or compartment-type rack (Fig. 9). Silverware and other small pieces should lay loosely on the bottom of a flat-bottom rack.
CLEANING This machine must be cleaned at least once each working day. Use only products formulated to be safe on stainless steel. 1. Press POWER. The machine will drain. When the display is no longer lit, open the door and remove any debris from the bottom of the tank. Do not allow food soil to accumulate on the tank bottom. 2. On LXeC and LXeH models, remove the lower rinse arm by unscrewing the thumb nut (Fig. 10).
MAINTENANCE Maintenance and regular care is important to maintain optimal results with your Hobart warewasher. DELIMING Deliming solution, rinse agents or any other kind of acid must not come in contact with bleach or rinse solution containing bleach used in chemical-sanitizing machines. Mixing may cause hazardous gas to form. This entire procedure must be followed step by step for safe and satisfactory results.
TROUBLESHOOTING This section outlines various symptoms and possible causes that may be encountered in the event of abnormal machine operation. If symptoms persist after possible causes have been checked, service may be required. Symptom Possible Causes No machine operation (no display). 1. Machine OFF - turn machine ON. 2. Blown fuse or circuit breaker off at power supply. 3. Cord not plugged in (corded models only) No machine operation (with display). 1. Display: "DOOR OPEN" - open and close door.
Symptom Possible Causes Unexpected results on dishes. 1. Etching - usually caused by any combination of high temperatures, soft water, soft glass, or high alkaline washing solutions. 2. Tarnishing - avoid washing silver, silver plates, and pewter in chemical sanitizing machines. 3. Pitting - stainless steel may pit with lengthy contact of foods containing salt, fruit juices, vinegar, etc. Wash immediately. 4. Black or gray marks - may have been rubbed with aluminum. 5.
