7.3 Notes for optimum wash results

The rinse result is significantly affected by the water quality. The minerals dissolved in the water become visible on the washware in the form of spots and streaks during the drying process.

If the mineral content is high, we recommend the use of a HOBART HYDROLINE demineralising unit.

Before washing new glasses the first time with a commercial glass washer, intensive basic cleaning is mandatory to reduce the greasy film which is on most glasses for protection during production. We recommend this basic clean is carried out by hand (wear gloves) with a higher detergent concentration (minimum 10 g/l) in a sink using a brush. Alternatively, the programme described in section 7.10 can also be used.

9.2 Remedying the problem

9.2.1 Poor wash result

Nature of the problemPossible causeRemedy
Wash ware not clean. Wash arm stiff (must rotate easily by hand). Remove wash arms and clean them thoroughly. Also check water outlet from machine to wash arm is clear.
Wash arm nozzles are clogged (visual check). Remove wash arm, remove cleaning caps and rinse wash arm thoroughly until all soiling is removed. Replace cleaning caps.
Rinse nozzles clogged (usually by lime deposit). Remove rinse arms and descale them in separate container. Check site softening system for function.
Detergent concentration is too low or too high. Check detergent concentration setting.
Coarse strainer clogged. Remove, empty and clean strainer.
Fine strainer clogged or obstructed by lime deposits. Remove fine strainer. If heavily soiled, soak in a vinegar solution. Then clean it thoroughly with a brush until the pores are free. The fine strainer should generally be cleaned daily (see operating instructions).
Wrong programme selected for heavily soiled wash ware. Select programme with longer wash cycle.
Wash ware does not dry properly. Wash ware still greasy. Detergent concentration too low: increase (see operation instructions). Check if detergent is appropriate. If not, choose a stronger one.
Drain contaminated water and refill machine. Clear wash ware more thoroughly beforehand.
Nature of the problemPossible causeRemedy
Streaks and spots on wash ware. Rack is not suitable for type of dishes (sloping). Use appropriate racks to create a sloping position which allows water to drain away from cavities.
Wash ware remains in the machine too long at the end of wash cycle. Remove wash ware as soon as cycle is completed to enable it to dry.
Hard water or high mineral content. Check water quality. Every local water works holds data on the composition of the water they supply and will provide these on request. Reference values: Ideal calcium value: 0 – 3°d (total hardness). Ideal mineral content value: for glasses, max. conductivity 100 µS/cm, for dishes, still viable to max. 400 µS/cm.
Rack is not suitable for type of dishes (sloping). Use appropriate racks to create a sloping position which allows water to drain away from cavities.
Machines with integrated softener: use of wrong salt (e.g. tablets). Do not use salt tablets.
Glasses are totally or partially cloudy. Surface of glasses is rough and porous, this is called glass corrosion. Use new glasses, this is not caused by a malfunction on the machine.
Glass/dish breakage. Use of unsuitable dish or glass racks. Use suitable racks.
Machine switches off suddenly during operation. Machine coupled to a maximum system or locked against other current consumers. A site fuse has tripped. Have machine connected separately (electrician!). Check site fuses.

10 Maintenance

In order to maintain the warranty, as well as a permanently safe, efficient, and trouble-free operation of the machine(s), the required maintenance must be carried out by authorized service technicians. We therefore recommend the conclusion of an inspection and maintenance contract, which guarantees qualified support by specially trained service technicians according to a time schedule based on the operating conditions.

Genuine spare parts must be used for repairs and wearing part replacements. Wearing parts include dosing hoses, rinse arm bearings, etc. In Germany, your HOBART machines are governed by the Ordinance on Industrial Health and Safety and must be inspected by a qualified electrician in accordance with the intervals specified by the Institute for Work and Health of the German Social Accident Insurance [DGUV V3 (BGV A3)].

11 Disposal

The machine operator is responsible for disposing of the machine and its operating materials correctly and in accordance with environmental regulations. Both national and local legal provisions and regulations must be observed!

With respect to fluorine-containing coolants in machines with heat pumps, the requirements of Regulation (EC) No. 517/2014 and supplementary national legislation must be observed in Europe.

We recommend assigning a specialist company for disposal. Alternatively, Hobart can take back the machine and its operating materials.

12 Product disclaimer

Installations and repairs carried out by non-authorized technicians or using non-genuine spare parts, and any technical alterations to the machine not approved by the manufacturer will invalidate the manufacturer's warranty and product liability.
